ModularAccountV2 is recommended as a cheap and advanced option, but other types like LightAccount, MultiOwnerLightAccount, and MultiOwnerModularAccount are available. Be aware that changing the account type will deploy a different account, and upgrades may be necessary if switching after deployment. +- Handle Bundler and RPC Traffic: Developers might need to use different RPC providers for bundler traffic and node traffic. This can be achieved by leveraging the split transport when calling createSmartAccountClient. +- Configure Gas and Fee Estimation: Depending on the RPC provider, custom logic for gasEstimator and feeEstimator properties might be required when calling createSmartAccountClient. Consult the provider for the correct logic. Alchemy provides alchemyFeeEstimator for estimating transaction fees. +- Manage Paymasters for Gas Sponsorship: The SmartAccountClient is unopinionated about the paymaster used. Configuration is done using the paymasterAndData config option when calling createSmartAccountClient. +- Implement Gas Abstraction: Consider sponsoring gas fees for users using the Gas Manager API. This involves creating a gas policy in the Gas Manager dashboard and linking its policyId to the client configuration. +- Integrate Third-Party Paymasters: If using a third-party paymaster, ensure proper configuration, which might involve providing custom logic for gasEstimator and paymasterAndData. For ERC-7677 compliant paymasters, the erc7677Middleware can simplify integration. +- Utilize viem for Blockchain Interactions: Account Kit is built on viem, an Ethereum JavaScript library. Developers should familiarize themselves with viem's concepts like createClient for building clients, getContract for contract interactions, and actions for various blockchain operations. +- Understand User Operations: Be familiar with the structure of UserOperationRequest and the process of sending and waiting for user operations to be mined. Implement logic to handle potential failures and resubmit user operations using "drop and replace" if necessary. \ No newline at end of file diff --git a/.agent/rules/buysellrules.md b/.agent/rules/buysellrules.md new file mode 100644 index 000000000..db2ca7792 --- /dev/null +++ b/.agent/rules/buysellrules.md @@ -0,0 +1,24 @@ +--- +description: how to buy and sell metokens via the vault address. +globs: +alwaysApply: false +--- + +What I found: +The ERC20 approve is correctly executed via a UserOperation and confirmed on-chain. +The allowance is immediately visible via standard allowance() reads. +I validated allowance end-to-end with a minimal test: +The Smart Account performs approve(spender, amount) via UserOp +The approved spender successfully calls transferFrom and the transaction completes with status: success +This confirms allowance propagation is correct and the network is not “missing” the approval state in this scenario. + +Why the mint flow fails +In the failing mint() path, allowance is being set for Contract A (for example the Diamond or meToken), but the actual transferFrom is executed by Contract B (for example a downstream vault or router). +Since ERC20 allowances are checked against msg.sender, this produces a legitimate ERC20: insufficient allowance revert even though allowance exists for a different contract. +This also explains why waiting 30 to 60+ seconds does not help and why simulation consistently reports insufficient allowance. + +Additional verification +To rule out bundler-specific behavior, I also tested unrelated interactions (including approve + transferFrom and other contract calls).

A destination sink to write your data to. In this example, we will use [the PostgreSQL Sink](/mirror/sinks/postgres) + +## Introduction + +In order to stream all the ERC-20 Transfers of a chain there are two potential methods available: + +1. Use the readily available ERC-20 dataset for the chain you are interested in: this is the easiest and quickest method to get you streaming token transfers into your sink of choice with minimum code. +2. Build the ERC-20 Transfers pipeline from scratch using raw or decoded logs: this method takes more code and time to implement but it's a great way to learn about how you can use decoding functions in case you + want to build more customized pipelines. + +Let's explore both method below with more detail: + +## Using the ERC-20 Transfers Source Dataset + +Every EVM chain has its own ERC-20 dataset available for you to use as source in your pipelines. You can check this by running the `goldsky dataset list` command and finding the EVM of your choice. +For this example, let's use `apex` chain and create a simple pipeline definition using its ERC-20 dataset that writes the data into a PostgreSQL instance: + +```yaml apex-erc20-transfers.yaml theme={null} +name: apex-erc20-pipeline +resource_size: s +apiVersion: 3 +sources: + apex.erc20_transfers: + dataset_name: apex.erc20_transfers + version: 1.0.0 + type: dataset + start_at: earliest +transforms: {} +sinks: + postgres_apex.erc20_transfers_public_apex_erc20_transfers: + type: postgres + table: apex_erc20_transfers + schema: public + secret_name: + description: "Postgres sink for Dataset: apex.erc20_transfers" + from: apex.erc20_transfers +``` + + + If you copy and use this configuration file, make sure to update: 1. Your + `secretName`. If you already [created a secret](/mirror/manage-secrets), you + can find it via the [CLI command](/reference/cli#secret) `goldsky secret + list`. 2. The schema and table you want the data written to, by default it + writes to `public.apex_erc20_transfers`. + + +You can start above pipeline by running: + +```bash theme={null} +goldsky pipeline start apex-erc20-pipeline.yaml +``` + +Or + +```bash theme={null} +goldsky pipeline apply apex-erc20-pipeline.yaml --status ACTIVE +``` + +That's it! You should soon start seeing ERC-20 token transfers in your database. + +## Building ERC-20 Transfers from scratch using logs + +In the previous method we just explored, the ERC-20 datasets that we used as source to the pipeline encapsulates all the decoding logic that's explained in this section. +Read on if you are interested in learning how it's implemented in case you want to consider extending or modifying this logic yourself. + +There are two ways that we can go about building this token transfers pipeline from scratch: + +1. Use the `raw_logs` Direct Indexing dataset for that chain in combination with [Decoding Transform Functions](/reference/mirror-functions/decoding-functions) using the ABI of a specific ERC-20 Contract. +2. Use the `decoded_logs` Direct Indexing dataset for that chain in which the decoding process has already been done by Goldsky. This is only available for certain chains as you can check in [this list](/mirror/sources/direct-indexing). + +We'll primarily focus on the first decoding method using `raw_logs` and decoding functions as it's the default and most used way of decoding; we'll also present an example using `decoded_logs` and highlight the differences between the two. + +### Building ERC-20 Tranfers using Decoding Transform Functions + +In this example, we will stream all the `Transfer` events of all the ERC-20 Tokens for the [Scroll chain](https://scroll.io/). To that end, we will dinamically fetch the ABI of the USDT token from the Scrollscan API (available [here](https://api.scrollscan.com/api?module=contract\&action=getabi\&address=0xc7d86908ccf644db7c69437d5852cedbc1ad3f69)) +and use it to identify all the same events for the tokens in the chain. We have decided to use the ABI of USDT token contract for this example but any other ERC-20 compliant token would also work. + +We need to differentiate ERC-20 token transfers from ERC-721 (NFT) transfers since they have the same event signature in decoded data: `Transfer(address,address,uint256)`. +However, if we look closely at their event definitions we can appreciate that the number of topics differ: + +* [ERC-20](https://ethereum.org/en/developers/docs/standards/tokens/erc-20/): `event Transfer(address indexed _from, address indexed _to, uint256 _value)` +* [ERC-721](https://ethereum.org/en/developers/docs/standards/tokens/erc-721/): `event Transfer(address indexed _from, address indexed _to, uint256 indexed _tokenId)` + +ERC-20 Transfer events have three topics (one topic for event signature + 2 topics for the indexed params). +NFTs on the other hand have four topics as they have one more indexed param in the event signature. +We will use this as a filter in our pipeline transform to only transfer ERC-20 Transfer events. + +Let's now see all these concepts applied in an example pipeline definition: + +#### Pipeline Definition + + + + ```yaml scroll-erc20-transfers.yaml theme={null} + name: scroll-erc20-transfers + apiVersion: 3 + sources: + my_scroll_mainnet_raw_logs: + type: dataset + dataset_name: scroll_mainnet.raw_logs + version: 1.0.0 + transforms: + scroll_decoded: + primary_key: id + # Fetch the ABI from scrollscan for USDT + sql: > + SELECT + *, + _gs_log_decode( + _gs_fetch_abi('https://api.scrollscan.com/api?module=contract&action=getabi&address=0xc7d86908ccf644db7c69437d5852cedbc1ad3f69', 'etherscan'), + `topics`, + `data` + ) AS `decoded` + FROM my_scroll_mainnet_raw_logs + WHERE topics LIKE '0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef%' + AND SPLIT_INDEX(topics, ',', 3) IS NULL + scroll_clean: + primary_key: id + # Clean up the previous transform, unnest the values from the `decoded` object + sql: > + SELECT + *, + decoded.event_params AS `event_params`, + decoded.event_signature AS `event_name` + FROM scroll_decoded + WHERE decoded IS NOT NULL + AND decoded.event_signature = 'Transfer' + scroll_20_transfers: + primary_key: id + sql: > + SELECT + id, + address AS token_id, + lower(event_params[1]) AS sender, + lower(event_params[2]) AS recipient, + lower(event_params[3]) AS `value`, + event_name, + block_number, + block_hash, + log_index, + transaction_hash, + transaction_index + FROM scroll_clean + sinks: + scroll_20_sink: + type: postgres + table: erc20_transfers + schema: mirror + secret_name: + description: Postgres sink for ERC20 transfers + from: scroll_20_transfers + ``` + + + + ```yaml scroll-erc20-transfers.yaml theme={null} + sources: + - type: dataset + referenceName: scroll_mainnet.raw_logs + version: 1.0.0 + transforms: + - referenceName: scroll_decoded + type: sql + primaryKey: id + # Fetch the ABI from scrollscan for USDT + sql: > + SELECT + *, + _gs_log_decode( + _gs_fetch_abi('https://api.scrollscan.com/api?module=contract&action=getabi&address=0xc7d86908ccf644db7c69437d5852cedbc1ad3f69', 'etherscan'), + `topics`, + `data` + ) AS `decoded` + WHERE topics LIKE '0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef%' + AND SPLIT_INDEX(topics, ',', 3) IS NULL + FROM scroll_mainnet.raw_logs + + - referenceName: scroll_clean + primaryKey: id + type: sql + # Clean up the previous transform, unnest the values from the `decoded` object + sql: > + SELECT + *, + decoded.event_params AS `event_params`, + decoded.event_signature AS `event_name` + FROM scroll_decoded + WHERE decoded IS NOT NULL + AND decoded.event_signature = 'Transfer' + + - referenceName: scroll_20_transfers + primaryKey: id + type: sql + sql: > + SELECT + id, + address AS token_id, + lower(event_params[1]) AS sender, + lower(event_params[2]) AS recipient, + lower(event_params[3]) AS `value`, + event_name, + block_number, + block_hash, + log_index, + transaction_hash, + transaction_index + FROM scroll_clean + sinks: + - type: postgres + table: erc20_transfers + schema: mirror + secretName: + description: Postgres sink for ERC20 transfers + referenceName: scroll_20_sink + sourceStreamName: scroll_20_transfers + ``` + + + + + If you copy and use this configuration file, make sure to update: 1.

The schema and table you want the data written to, by default it + writes to `mirror.erc20_transfers`. + + +There are three transforms in this pipeline definition which we'll explain how they work: + +```sql Transform: scroll_decoded theme={null} +SELECT + *, + _gs_log_decode( + _gs_fetch_abi('https://api.scrollscan.com/api?module=contract&action=getabi&address=0xc7d86908ccf644db7c69437d5852cedbc1ad3f69', 'etherscan'), + `topics`, + `data` + ) AS `decoded` + FROM scroll_mainnet.raw_logs + WHERE topics LIKE '0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef%' + AND SPLIT_INDEX(topics, ',', 3) IS NULL +``` + +As explained in the [Decoding Contract Events guide](/mirror/guides/decoding-contract-events) we first make use of the `_gs_fetch_abi` function to get the ABI from Scrollscan and pass it as first argument +to the function `_gs_log_decode` to decode its topics and data. We store the result in a `decoded` [ROW](https://nightlies.apache.org/flink/flink-docs-stable/docs/dev/table/types/#row) which we unnest on the next transform. +We also limit the decoding to the relevent events using the topic filter and `SPLIT_INDEX` to only include ERC-20 transfers. + +* `topics LIKE '0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef%'`: `topics` is a comma separated string. Each value in the string is a hash. The first is the hash of the full event\_signature (including arguments), in our case `Transfer(address,address,uint256)` for ERC-20, which is hashed to `0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef`. We use `LIKE` to only consider the first signature, with a `%` at the end, which acts as a wildcard. +* `SPLIT_INDEX(topics, ',', 3) IS NULL`: as mentioned in the introduction, ERC-20 transfers share the same `event_signature` as ERC-721 transfers. The difference between them is the number of topics associated with the event. ERC-721 transfers have four topics, and ERC-20 transfers have three. + +```sql Transform: scroll_clean theme={null} +SELECT + *, + decoded.event_params AS `event_params`, + decoded.event_signature AS `event_name` + FROM scroll_decoded + WHERE decoded IS NOT NULL + AND decoded.event_signature = 'Transfer' +``` + +In this second transform, we take the `event_params` and `event_signature` from the result of the decoding. We then filter the query on: + +* `decoded IS NOT NULL`: to leave out potential null results from the decoder +* `decoded.event_signature = 'Transfer'`: the decoder will output the event name as event\_signature, excluding its arguments. We use it to filter only for Transfer events. + +```sql Transform: scroll_20_transfers theme={null} +SELECT + id, + address AS token_id, + lower(event_params[1]) AS sender, + lower(event_params[2]) AS recipient, + lower(event_params[3]) AS `value`, + event_name, + block_number, + block_hash, + log_index, + transaction_hash, + transaction_index + FROM scroll_clean +``` + +In this last transform we are essentially selecting all the Transfer information we are interested in having in our database. +We've included a number of columns that you may or may not need, the main columns needed for most purposes are: `id`, `address` (if you are syncing multiple contract addresses), `sender`, `recipient`, `token_id`, and `value`. + +* `id`: This is the Goldsky provided `id`, it is a string composed of the dataset name, block hash, and log index, which is unique per event, here's an example: `log_0x60eaf5a2ab37c73cf1f3bbd32fc17f2709953192b530d75aadc521111f476d6c_18` +* `address AS token_id`: We use the `lower` function here to lower-case the address to make using this data simpler downstream, we also rename the column to `token_id` to make it more explicit. +* `lower(event_params[1]) AS sender`: Here we continue to lower-case values for consistency. In this case we're using the first element of the `event_params` array (using a 1-based index), and renaming it to `sender`. Each event parameter maps to an argument to the `event_signature`. +* `lower(event_params[2]) AS recipient`: Like the previous column, we're pulling the second element in the `event_params` array and renaming it to `recipient`. +* `lower(event_params[3]) AS value`: We're pulling the third element in the `event_params` array and renaming it to `value` to represent the amount of the token\_id sent in the transfer. + +Lastly, we are also adding more block metadata to the query to add context to each transaction: + +``` +event_name, +block_number, +block_hash, +log_index, +transaction_hash, +transaction_index +``` + +It's worth mentioning that in this example we are interested in all the ERC-20 Transfer events but if you would like to filter for specific contract addresses you could simply add a `WHERE` filter to this query with address you are interested in, like: `WHERE address IN ('0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D', '0xdac17f958d2ee523a2206206994597c13d831ec7')` + +#### Deploying the pipeline + +Our last step is to deploy this pipeline and start sinking ERC-20 transfer data into our database. Assuming we are using the same file name for the pipeline configuration as in this example, +we can use the [CLI pipeline create command](/reference/cli#pipeline-create) like this: + +`goldsky pipeline create scroll-erc20-transfers --definition-path scroll-erc20-transfers.yaml` + +After some time, you should see the pipeline start streaming Transfer data into your sink. + + + Remember that you can always speed up the streaming process by + [updating](/reference/cli#pipeline-update) the resourceSize of the pipeline + + +Here's an example transfer record from our sink: + +| id | token\_id | sender | recipient | value | event\_name | block\_number | block\_hash | log\_index | transaction\_hash | transaction\_index | +| -------------------------------------------------------------------------- | ------------------------------------------ | ------------------------------------------ | ------------------------------------------ | ----------------- | ----------- | ------------- | ------------------------------------------------------------------ | ---------- | ------------------------------------------------------------------ | ------------------ | +| log\_0x666622ad5c04eb5a335364d9268e24c64d67d005949570061d6c150271b0da12\_2 | 0x5300000000000000000000000000000000000004 | 0xefeb222f8046aaa032c56290416c3192111c0085 | 0x8c5c4595df2b398a16aa39105b07518466db1e5e | 22000000000000006 | Transfer | 5136 | 0x666622ad5c04eb5a335364d9268e24c64d67d005949570061d6c150271b0da12 | 2 | 0x63097d8bd16e34caacfa812d7b608c29eb9dd261f1b334aa4cfc31a2dab2f271 | 0 | + +We can find this [transaction in Scrollscan](https://scrollscan.com/tx/0x63097d8bd16e34caacfa812d7b608c29eb9dd261f1b334aa4cfc31a2dab2f271).

Your `secretName`. If you already [created a secret](/mirror/manage-secrets), you can find it via the [CLI command](/reference/cli#secret) `goldsky secret list`. + 2. The schema and table you want the data written to, by default it writes to `mirror.erc20_transfers`. + + + +You can appreciate that it's pretty similar to the inline decoding pipeline method but here we simply create a transform which does the filtering based on the `raw_log.topics` just as we did on the previous method. + +Assuming we are using the same filename for the pipeline configuration as in this example and that you have added your own [secret](/mirror/manage-secrets) +we can deploy this pipeline with the [CLI pipeline create command](/reference/cli#pipeline-create): + +`goldsky pipeline create ethereum-erc20-transfers --definition-path ethereum-decoded-logs-erc20-transfers.yaml` + +## Conclusion + +In this guide, we have learnt how Mirror simplifies streaming ERC-20 Transfer events into your database. + +We have first looked into the easy way of achieving this, simply by making use of the readily available ERC-20 dataset of the EVM chaina and using its as the source to our pipeline. + +Next, we have deep dived into the standard decoding method using Decoding Transform Functions, implementing an example on Scroll chain. +We have also looked into an example implementation using the decoded\_logs dataset for Ethereum. Both are great decoding methods and depending on your use case and dataset availability you might prefer one over the other. + +With Mirror, developers gain flexibility and efficiency in integrating blockchain data, opening up new possibilities for applications and insights. Experience the transformative power of Mirror today and redefine your approach to blockchain data integration. + +Can't find what you're looking for?

Traditionally these GraphQL +interfaces are completely public and can be accessed by anyone. Goldsky supports public GraphQL endpoints for both +subgraphs and their tags. + +## Public endpoints + +For example, in the Goldsky managed community project there exists the `uniswap-v3-base/1.0.0` subgraph with a tag of `prod`. +This subgraph has a [public endpoint](https://api.goldsky.com/api/public/project_cl8ylkiw00krx0hvza0qw17vn/subgraphs/uniswap-v3-base/1.0.0/gn) +and the tag `prod` also has a [public endpoint](https://api.goldsky.com/api/public/project_cl8ylkiw00krx0hvza0qw17vn/subgraphs/uniswap-v3-base/prod/gn). + +Uniswap public subgraph endpoint for prod tag + +In general, public endpoints come in the form of `https://api.goldsky.com/api/public//subgraphs///gn` + +Goldsky adds rate limiting to all public endpoints to prevent abuse. We currently have a default rate limit of 50 requests per 10 seconds. +This can be unlocked by contacting us at [support@goldsky.com](mailto:support@goldsky.com). + +One major downside of public endpoints is that they are completely public and can be accessed by anyone. This means that +anyone can query the data in the subgraph and potentially abuse the endpoint. This is why we also support private endpoints. + +## Private endpoints + +Private endpoints are only accessible by authenticated users. This means that you can control who can access the data in +your subgraph. Private endpoints are only available to users who have been granted access to the subgraph. Accessing +a private endpoint requires sending an `Authorization` header with the GraphQL request. The value of the `Authorization` +header should be in the form of `Bearer ` where the `token` is an API token that has been generated through +[Goldsky project general settings](https://app.goldsky.com/dashboard/settings#general). Remember that API tokens are scoped to specific projects. This means an API +token for `projectA` cannot be used to access the private endpoints of subgraphs in `projectB`. + +Private endpoints can be toggled on and off for each subgraph and tag. This means that you can have a mix of public and +private endpoints for your subgraph. For example, you can have a public endpoint for your subgraph and a private endpoint +for a specific tag. + +Here's an example of how to access a private endpoint using the GraphiQL interface: + +GraphiQL query with Authorization header + +Private subgraphs endpoints follow the same format as public subgraph endpoints except they start with `/api/private` +instead of `/api/public`. For example, the private endpoint for the `prod` tag of the `uniswap-v3-base/1.0.0` subgraph +would be `https://api.goldsky.com/api/private/project_cl8ylkiw00krx0hvza0qw17vn/subgraphs/uniswap-v3-base/1.0.0/gn`. + +### Revoking access + +To revoke access to a private endpoint you can simply delete the API token that was used to access the endpoint. If you +don't know which key is used to access the endpoint, you'll have to revoke all API tokens for all users that have access +to the project. + +## Enabling and disabling public and private endpoints + +By default, all new subgraphs and their tags come with the public endpoint enabled and the private endpoint disabled. +Both of these settings can be changed using the CLI and the webapp. To change either setting, you must have [`Editor` permissions](../rbac). + +### CLI + +To toggle one of these settings using the CLI you can use the `goldsky subgraph update` command with the +`--public-endpoint ` flag and/or the `--private-endpoint ` flag. Here's a complete example +disabling the public endpoint and enabling the private endpoint for the `prod` tag of the `uniswap-v3-base/1.0.0` subgraph: + +```bash theme={null} +goldsky subgraph update uniswap-v3-base/prod --public-endpoint disabled --private-endpoint enabled +``` + +### Dashboard + +To toggle one of these settings using the dashboard webapp you can navigate to the subgraph detail page and use the relevant +toggles to enable or disable the public or private endpoints of the subgraph or its tags. + +[//]: # "TODO: add a screenshot of this once the implementation and design are complete" + +### Errors + +Goldsky does not enforce CORS on our GraphQL endpoints. If you see an error that references CORS, or an error with the response code 429, you're likely seeing an issue with rate limiting.

The name most often associated with the meToken is defaulted to user's self.id username. + +Example: Username, Bob Hope, might set the name of his meToken to Bob's meToken and the symbol to $BOB. On our frontend, we would not typically display Bob's meToken anywhere. We would instead use Bob Hope && $BOB. + + + +ABI + + + +Market Data + + + +TVL + +The TVL is the total value locked of the market of a person’s meToken. It is our equivalent of a market cap.

This is why you will find references to each format in each yaml file + presented across the documentation. Feel free to use whichever is more + comfortable for you but we encourage you to start migrating to v3 format. + + +## Overview + +A Mirror Pipeline defines flow of data from `sources -> transforms -> sinks`. It is configured in a `yaml` file which adheres to Goldsky's pipeline schema. + +The core logic of the pipeline is defined in `sources`, `transforms` and `sinks` attributes. + +* `sources` represent origin of the data into the pipeline. +* `transforms` represent data transformation/filter logic to be applied to either a source and/or transform in the pipeline. +* `sinks` represent destination for the source and/or transform data out of the pipeline. + +Each `source` and `transform` has a unique name which is referenceable in other `transform` and/or `sink`, determining dataflow within the pipeline. + +While the pipeline is configured in yaml, [goldsky pipeline CLI commands](/reference/cli#pipeline) are used to take actions on the pipeline such as: `start`, `stop`, `get`, `delete`, `monitor` etc. + +Below is an example pipeline configuration which sources from `base.logs` Goldsky dataset, filters the data using `sql` and sinks to a `postgresql` table: + + + + ```yaml base-logs.yaml theme={null} + apiVersion: 3 + name: base-logs-pipeline + resource_size: s + sources: + base.logs: + dataset_name: base.logs + version: 1.0.0 + type: dataset + description: Enriched logs for events emitted from contracts. Contains the contract address, data, topics, decoded event and metadata for blocks and transactions. + display_name: Logs + transforms: + filter_logs_by_block_number: + sql: SELECT * FROM base.logs WHERE block_number > 5000 + primary_key: id + sinks: + postgres_base_logs: + type: postgres + table: base_logs + schema: public + secret_name: GOLDSKY_SECRET + description: "Postgres sink for: base.logs" + from: filter_logs_by_block_number + ``` + + + Keys in v3 format for sources, transforms and sinks are user provided + values. In the above example, the source reference name `base.logs` + matches the actual dataset name. This is the convention that you'll + typically see across examples and autogenerated configurations. However, + you can use a custom name as the key. + + + + + ```yaml base-logs.yaml theme={null} + name: base-logs-pipeline + resource_size: s + apiVersion: 3 + definition: + sources: + - referenceName: base.logs + type: dataset + version: 1.0.0 + transforms: [] + sinks: + - type: postgres + table: base_logs + schema: public + secretName: GOLDSKY_SECRET + description: 'Postgres sink for: base.logs' + sourceStreamName: base.logs + referenceName: postgres_base_logs + ``` + + + +You can find the complete Pipeline configuration schema in the [reference](/reference/config-file/pipeline) page. + +## Development workflow + +Similar to the software development workflow of `edit -> compile -> run`, there's an implict iterative workflow of `configure -> apply -> monitor` for developing pipelines. + +1. `configure`: Create/edit the configuration yaml file. +2. `apply`: Apply the configuration aka run the pipeline. +3. `monitor`: Monitor how the pipeline behaves. This will help create insights that'll generate ideas for the first step. + +Eventually, you'll end up with a configuration that works for your use case. + +Creating a Pipeline configuration from scratch is challenging. However, there are tools/guides/examples that make it easier to [get started](/mirror/create-a-pipeline). + +## Understanding Pipeline Runtime Lifecycle + +The `status` attribute represents the desired status of the pipeline and is provided by the user. Applicable values are: + +* `ACTIVE` means the user wants to start the pipeline. +* `INACTIVE` means the user wants to stop the pipeline. +* `PAUSED` means the user wants to save-progress made by the pipeline so far and stop it. + +A pipeline with status `ACTIVE` has a runtime status as well. Runtime represents the execution of the pipeline. Applicable runtime status values are: + +* `STARTING` means the pipeline is being setup. +* `RUNNING` means the pipeline has been setup and is processing records. +* `FAILING` means the pipeline has encountered errors that prevents it from running successfully. +* `TERMINATED` means the pipeline has failed and the execution has been terminated. + +There are several [goldsky pipeline CLI commands](/reference/config-file/pipeline#pipeline-runtime-commands) that help with pipeline execution. + +For now, let's see how these states play out on successful and unsuccessful scenarios. + +### Successful pipeline lifecycle + +In this scenario the pipeline is succesfully setup and processing data without encountering any issues. +We consider the pipeline to be in a healthy state which translates into the following statuses: + +* Desired `status` in the pipeline configuration is `ACTIVE` +* Runtime Status goes from `STARTING` to `RUNNING` + +
+ ```mermaid theme={null} + stateDiagram-v2 + state ACTIVE { + [*] --> STARTING + STARTING --> RUNNING + } + ``` +
+ +Let's look at a simple example below where we configure a pipeline that consumes Logs from Base chain and streams them into a Postgres database: + + + + ```yaml base-logs.yaml theme={null} + name: base-logs-pipeline + resource_size: s + apiVersion: 3 + sources: + base.logs: + dataset_name: base.logs + version: 1.0.0 + type: dataset + description: Enriched logs for events emitted from contracts.

We can confirm this using `goldsky pipeline list`: + +``` +❯ goldsky pipeline list +✔ Listing pipelines +──────────────────────────────────────── +│ Name │ Version │ Status │ Resource │ +│ │ │ │ Size │ +│─────────────────────────────────────── +│ base-logs-pipeline │ 1 │ ACTIVE │ s │ +──────────────────────────────────────── + +``` + +We can then check the runtime status of this pipeline using the `goldsky pipeline monitor base-logs-pipeline` command: + + + +We can see how the pipeline starts in `STARTING` status and becomes `RUNNING` as it starts processing data successfully into our Postgres sink. +This pipeline will start processing the historical data of the source dataset, reach its edge and continue streaming data in real time until we either stop it or it encounters error(s) that interrupts it's execution. + +### Unsuccessful pipeline lifecycle + +Let's now consider the scenario where the pipeline encounters errors during its lifetime and ends up failing. + +There can be multitude of reasons for a pipeline to encounter errors such as: + +* secrets not being correctly configured +* sink availability issues +* policy rules on the sink preventing the pipeline from writing records +* resource size incompatiblity +* and many more + +These failure scenarios prevents a pipeline from getting-into or staying-in a `RUNNING` runtime status. + +

+ +A Pipeline can be in an `ACTIVE` desired status but a `TERMINATED` runtime status in scenarios that lead to terminal failure. + +Let's see an example where we'll use the same configuration as above but set a `secret_name` that does not exist. + + + + ```yaml bad-base-logs.yaml theme={null} + name: bad-base-logs-pipeline + resource_size: s + apiVersion: 3 + sources: + base.logs: + dataset_name: base.logs + version: 1.0.0 + type: dataset + description: Enriched logs for events emitted from contracts.

Mirror pipelines expose: + +1. Runtime status and error messages +2. Logs emitted by the pipeline +3. Metrics on `Records received`, which counts all the records the pipeline has received from source(s) and, `Records written` which counts all records the pipeline has written to sink(s). +4. [Email notifications](/mirror/about-pipeline#email-notifications) + +Runtime status, error messages and metrics can be seen via two methods: + +1. Pipeline dashboard at `https://app.goldsky.com/dashboard/pipelines/stream//` +2. `goldsky pipeline monitor ` CLI command + +Logs can only be seen in the pipeline dashboard. + +Mirror attempts to surface appropriate and actionable error message and status for users, however, there is always room for imporovements. Please [reachout](/getting-support) if you think the experience can be improved. + +### Email notifications + +If a pipeline fails terminally the project members will get notified via an email. + + + +You can configure this nofication in the [Notifications section](https://app.goldsky.com/dashboard/settings#notifications) of your project + +## Error handling + +There are two broad categories of errors. + +**Pipeline configuration schema error** + +This means the schema of the pipeline configuration is not valid. These errors are usually caught before pipeline execution. Some possible scenarios: + +* a required attribute is missing +* transform SQL has syntax errors +* pipeline name is invalid + +**Pipeline runtime error** + +This means the pipeline encountered error during execution at runtime. + +Some possible scenarios: + +* credentails stored in the secret are incorrect or do not have needed access privilages +* sink availability issues +* poison-pill record that breaks the business logic in the transforms +* `resource_size` limitation + +Transient errors are automatically retried as per retry-policy (for upto 6 hours) whearas non-transient ones immediately terminate the pipeline. + +While many errors can be resolved by user intervention, there is a possibility of platform errors as well. Please [reachout to support](/getting-support) for investigation. + +## Resource sizing + +`resource_size` represents the compute (vCPUs and RAM) available to the pipeline. There are several options for pipeline sizes: `s, m, l, xl, xxl`. This attribute influences [pricing](/pricing/summary#mirror) as well. + +Resource sizing depends on a few different factors such as: + +* number of sources, transforms, sinks +* expected amount of data to be processed. +* transform sql involves joining multiple sources and/or transforms + +Here's some general information that you can use as reference: + +* A `small` resource size is usually enough in most use case: it can handle full backfill of small chain datasets and write to speeds of up to 300K records per second. For pipelines using + subgraphs as source it can reliably handle up to 8 subgraphs. +* Larger resource sizes are usually needed when backfilling large chains or when doing large JOINS (example: JOIN between accounts and transactions datasets in Solana) +* It's recommended to always follow a defensive approach: start small and scale up if needed. + +## Snapshots + +A Pipeline snapshot captures a point-in-time state of a `RUNNING` pipeline allowing users to resume from it in the future. + +It can be useful in various scenarios: + +* evolving your `RUNNING` pipeline (eg: adding a new source, sink) without losing progress made so far. +* recover from new bug introductions where the user fix the bug and resume from an earlier snapshot to reprocess data. + +Please note that snapshot only contains info about the progress made in reading the source(s) and the sql transform's state. It isn't representative of the state of the source/sink. For eg: if all data in the sink database table is deleted, resuming the pipeline from a snapshot does not recover it. + +Currently, a pipeline can only be resumed from the latest available snapshot. If you need to resume from older snapshots, please [reachout to support](/getting-support) + +Snapshots are closely tied to pipeline runtime in that all [commands](/reference/config-file/pipeline#pipeline-runtime-commands) that changes pipeline runtime has options to trigger a new snapshot and/or resume from the latest one. + +```mermaid theme={null} +%%{init: { 'gitGraph': {'mainBranchName': 'myPipeline-v1'}, 'theme': 'default' , 'themeVariables': { 'git0': '#ffbf60' }}}%% +gitGraph + commit id: " " type: REVERSE tag:"start" + commit id: "snapshot1" + commit id: "snapshot2" + commit id: "snapshot3" + commit id: "snapshot4" tag:"stop" type: HIGHLIGHT + branch myPipeline-v2 + commit id: "snapshot4 " type: REVERSE tag:"start" +``` + +### When are snapshots taken? + +1. When updating a `RUNNING` pipeline, a snapshot is created before applying the update. This is to ensure that there's an up-to-date snapshot in case the update introduces issues. +2. When pausing a pipeline. +3. Automatically on regular intervals. For `RUNNING` pipelines in healthy state, automatic snapshots are taken every 4 hours to ensure minimal data loss in case of errors. +4. Users can request snapshot creation via the following CLI command: + +* `goldsky pipeline snapshot create ` +* `goldsky pipeline apply --from-snapshot new` +* `goldsky pipeline apply --save-progress true` (CLI version \< `11.0.0`) + +5. Users can list all snapshots in a pipeline via the following CLI command: + +* `goldsky pipeline snapshot list ` + +### How long does it take to create a snapshot + +The amount of time it takes for a snapshot to be created depends largly on two factors. First, the amount of state accumulated during pipeline execution. Second, how fast records are being processed end-end in the pipeline. + +In case of a long running snapshot that was triggered as part of an update to the pipeline, any future updates are blocked until snapshot is completed. Users do have an option to cancel the update request. + +There is a scenario where the the pipeline was healthy at the time of starting the snapshot however, became unhealthy later preventing snapshot creation. Here, the pipeline will attempt to recover however, may need user intervention that involves restarting from last successful snapshot. + +### Scenarios and Snapshot Behavior + +Happy Scenario: + +* Suppose a pipeline is at 50% progress, and an automatic snapshot is taken. +* The pipeline then progresses to 60% and is in a healthy state. If you pause the pipeline at this point, a new snapshot is taken. +* You can later start the pipeline from the 60% snapshot, ensuring continuity from the last known healthy state. + +Bad Scenario: + +* If the pipeline reaches 50%, and an automatic snapshot is taken. +* It then progresses to 60% but enters a bad state. Attempting to pause the pipeline in this state will fail. +* If you restart the pipeline, it will resume from the last successful snapshot at 50%, there was no snapshot created at 60% + +Can't find what you're looking for?

This means every historical version of every entity is stored. To do this, each row has an `id`, `vid`, and `block_range`. + +When you update an entity in a subgraph mapping handler, a new row in the database is created with the same ID, but new VID and block\_range, and the old row's `block_range` is updated to have an end. + +By default, pipelines **deduplicate** on `id`, to show only the latest row per `id`. In other words, historical entity state is not kept in the sink database. This saves a lot of database space and makes for easier querying, as additional deduplication logic is not needed for simple queries. In a postgres database for example, the pipeline will update existing rows with the values from the newest block. + +This deduplication happens through setting the primary key in the data going through the pipeline. By default, the primary key is `id`. + +If historical data is desired, you can set the primary key to `vid` through a transform. + + + + ```yaml theme={null} + name: qidao-optimism-subgraph-to-postgrse + apiVersion: 3 + sources: + subgraph_account: + type: subgraph_entity + name: account + subgraphs: + - name: qidao-optimism + version: 1.1.0 + transforms: + historical_accounts: + sql: >- + select * from subgraph_account + primary_key: vid + sinks: + postgres_account: + type: postgres + table: historical_accounts + schema: goldsky + secret_name: A_POSTGRESQL_SECRET + from: historical_accounts + ``` + + + + ```yaml theme={null} + sources: + - type: subgraphEntity + # The deployment IDs you gathered above.

When defined, only these columns are serialized and sent. + # The handler's response is merged with the original full row. When omitted, all columns are sent. + payload_columns: Type.Optional(Type.Array(Type.String())) + ``` + + +### Payload columns + +The `payload_columns` attribute allows you to optimize bandwidth and control which data is sent to your external handler. + +**How it works:** + +1. When `payload_columns` is defined: + * Only the specified columns are serialized to JSON and sent to the external handler. + * A copy of the full original row is kept in memory. + * The handler's response is joined back with the original full row. + +2. When `payload_columns` is omitted: + * All columns are sent to the handler. + * Handler response replaces the entire row. + +**Purpose:** + +* **Bandwidth optimization:** Send only necessary columns to reduce payload size. +* **Data filtering:** Keep sensitive or large data local while only transmitting a subset. +* **Response merging:** Handler enriches the data, which is then merged with the original complete row. + +**Example:** + +If you have a row with columns `[transaction_hash, block_number, from_address, to_address, value, input_data, gas_used, gas_price, ...]` but only want to send `transaction_hash` and `from_address` to an API: + +```yaml theme={null} +transforms: + my_handler: + type: handler + primary_key: transaction_hash + url: http://example.com/enrich + from: ethereum.raw_transactions + payload_columns: ["transaction_hash", "from_address"] +``` + +Only `transaction_hash` and `from_address` are sent in the HTTP request. + +To filter data, return null in the json array in the response, but the array length must remain the same + +You can also send a new column back as part of that array to enrich the final result. The new column will be joined with the existing columns. + +### Schema override datatypes + +When overriding the schema of the data returned by the handler it’s important to get the datatypes for each column right. The schema\_override property is a map of column names to Flink SQL datatypes. + +Data types are nullable by default. If you need non-nullable types use \ NOT NULL. For example: STRING NOT NULL. + + + | Data Type | Notes | + | :------------- | :---------------------------------- | + | STRING | | + | BOOLEAN | | + | BYTE | | + | DECIMAL | Supports fixed precision and scale. | + | SMALLINT | | + | INTEGER | | + | BIGINT | | + | FLOAT | | + | DOUBLE | | + | TIME | Supports only a precision of 0. | + | TIMESTAMP | | + | TIMESTAMP\_LTZ | | + | ARRAY | | + | ROW | | + + +### Key considerations + +* **Schema Changes:** If the external handler’s output schema changes, you will need to redeploy the pipeline with the relevant schema\_override. +* **Failure Handling:** In case of failures, the pipeline retries requests indefinitely with exponential backoff. +* **Networking & Performance:** For optimal performance, deploy your handler in a region close to where the pipelines are deployed (we use aws `us-west-2`). Aim to keep p95 latency under 100 milliseconds for best results. +* **Latency vs Throughput:** Use lower batch\_size/batch\_flush\_interval to achive low latency and higher values to achieve high throughput (useful when backfilling/bootstraping). +* **Connection & Response times**: The maximum allowed response time is 5 minutes and the maximum allowed time to establish a connection is 1 minute. + +### In-order mode for external handlers + +In-Order mode allows for subgraph-style processing inside mirror. Records are emitted to the handler in the order that they appear on-chain. + +**How to get started** + +1. Make sure that the sources that you want to use currently support [Fast Scan](/mirror/sources/direct-indexing). If they don’t, submit a request to support. +2. In your pipeline definition specify the `filter` and `in_order` attributes for your source. +3. Declare a transform of type handler or a sink of type webhook. + +Simple transforms (e.g filtering) in between the source and the handler/webhook are allowed, but other complex transforms (e.g. aggregations, joins) can cause loss of ordering. + +**Example YAML config, with in-order mode** + + + ```YAML theme={null} + name: in-order-pipeline + sources: + ethereum.raw_transactions: + dataset_name: ethereum.raw_transactions + version: 1.1.0 + type: dataset + filter: block_number > 21875698 # [required] + in_order: true # [required] enables in-order mode on the given source and its downstream transforms and sinks. + sinks: + my_in_order_sink: + type: webhook + url: https://my-handler.com/process-in-order + headers: + WEBHOOK-SECRET: secret_two + secret_name: HTTPAUTH_SECRET_TWO + from: another_transform + my_sink: + type: webhook + url: https://python-handler.fly.dev/echo + from: ethereum.raw_transactions + ``` + + +**Example in-order webhook sink** + +```javascript theme={null} +const express = require('express'); +const { Pool } = require('pg'); + +const app = express(); +app.use(express.json()); + +// Database connection settings +const pool = new Pool({ + user: 'your_user', + host: 'localhost', + database: 'your_database', + password: 'your_password', + port: 5432, +}); + +async function isDuplicate(client, key) { + const res = await client.query("SELECT 1 FROM processed_messages WHERE key = $1", [key]); + return res.rowCount > 0; +} + +app.post('/webhook', async (req, res) => { + const client = await pool.connect(); + try { + await client.query('BEGIN'); + + const payload = req.body; + const metadata = payload.metadata || {}; + const data = payload.data || {}; + const op = metadata.op; + const key = metadata.key; + + if (!key || !op || !data) { + await client.query('ROLLBACK'); + return res.status(400).json({ error: "Invalid payload" }); + } + + if (await isDuplicate(client, key)) { + await client.query('ROLLBACK'); + return res.status(200).json({ message: "Duplicate request processed without write side effects" }); + } + + if (op === "INSERT") { + const fields = Object.keys(data); + const values = Object.values(data); + const placeholders = fields.map((_, i) => `$${i + 1}`).join(', '); + const query = `INSERT INTO my_table (${fields.join(', ')}) VALUES (${placeholders})`; + await client.query(query, values); + } else if (op === "DELETE") { + const conditions = Object.keys(data).map((key, i) => `${key} = $${i + 1}`).join(' AND '); + const values = Object.values(data); + const query = `DELETE FROM my_table WHERE ${conditions}`; + await client.query(query, values); + } else { + await client.query('ROLLBACK'); + return res.status(400).json({ error: "Invalid operation" }); + } + + await client.query("INSERT INTO processed_messages (key) VALUES ($1)", [key]); + await client.query('COMMIT'); + return res.status(200).json({ message: "Success" }); + } catch (e) { + await client.query('ROLLBACK'); + return res.status(500).json({ error: e.message }); + } finally { + client.release(); + } +}); + +app.listen(5000, () => { + console.log('Server running on port 5000'); +}); +``` + +**In-order mode tips** + +* To observe records in order, either have a single instance of your handler responding to requests OR introduce some coordination mechanism to make sure that only one replica of the service can answer at a time. +* When deploying your service, avoid having old and new instances running at the same time. Instead, discard the current instance and incur a little downtime to preserve ordering. +* When receiving messages that have already been processed in the handler (pre-existing idempotency key or previous index (e.g already seen block number)) **don't** introduce any side effects on your side, but **do** respond to the message as usual (i.e., processed messages for handlers, success code for webhook sink) so that the pipeline knows to keep going. + +### Useful tips + +Schema Changes: A change in the output schema of the external handler requires redeployment with schema\_override. + +* **Failure Handling:** The pipeline retries indefinitely with exponential backoff. +* **Networking:** Deploy the handler close to where the pipeline runs for better performance. +* **Latency:** Keep handler response times under 100ms to ensure smooth operation. + + +--- + +> To find navigation and other pages in this documentation, fetch the llms.txt file at: https://docs.goldsky.com/llms.txt + +# External Handler Transforms + +> Transforming data with an external http service. + +With external handler transforms, you can send data from your Mirror pipeline to an external service via HTTP and return the processed results back into the pipeline.

When doing many writes, inserts can slow down the process significantly if we're hitting resources limitations. + +### Bigger batch\_sizes for the inserts + +The `sink_buffer_max_rows` setting controls how many rows are batched into a single insert statement. Depending on the size of the events, you can increase this to help with write performance. `1000` is a good number to start with. The pipeline will collect data until the batch is full, or until the `sink_buffer_interval` is met. + +### Temporarily scale up the database + +Take a look at your database stats like CPU and Memory to see where the bottlenecks are. Often, big writes aren't blocked on CPU or RAM, but rather on network or disk I/O. + +For Google Cloud SQL, there are I/O burst limits that you can surpass by increasing the amount of CPU. + +For AWS RDS instances (including Aurora), the network burst limits are documented for each instance. A rule of thumb is to look at the `EBS baseline I/O` performance as burst credits are easily used up in a backfill scenario. + +# Provider Specific Notes + +### AWS Aurora Postgres + +When using Aurora, for large datasets, make sure to use `Aurora I/O optimized`, which charges for more storage, but gives you immense savings on I/O credits. If you're streaming the entire chain into your database, or have a very active subgraph, these savings can be considerable, and the disk performance is significantly more stable and results in more stable CPU usage pattern. + +### Supabase + +Supabase's direct connection URLs only support IPv6 connections and will not work with our default validation. There are two solutions + +1. Use `Session Pooling`. In the connection screen, scroll down to see the connection string for the session pooler. This will be included in all Supabase plans and will work for most people. However, sessions will expire, and may lead to some warning logs in your pipeline logs. These will be dealt with gracefully and no action is needed. No data will be lost due to a session disconnection. + + +2.

When doing many writes, inserts can slow down the process significantly if we're hitting resources limitations. + +### Bigger batch\_sizes for the inserts + +The `sink_buffer_max_rows` setting controls how many rows are batched into a single insert statement. Depending on the size of the events, you can increase this to help with write performance. `1000` is a good number to start with. The pipeline will collect data until the batch is full, or until the `sink_buffer_interval` is met. + +### Temporarily scale up the database + +Take a look at your database stats like CPU and Memory to see where the bottlenecks are. Often, big writes aren't blocked on CPU or RAM, but rather on network or disk I/O. + +For Google Cloud SQL, there are I/O burst limits that you can surpass by increasing the amount of CPU. + +For AWS RDS instances (including Aurora), the network burst limits are documented for each instance. A rule of thumb is to look at the `EBS baseline I/O` performance as burst credits are easily used up in a backfill scenario. + +# Provider Specific Notes + +### AWS Aurora Postgres + +When using Aurora, for large datasets, make sure to use `Aurora I/O optimized`, which charges for more storage, but gives you immense savings on I/O credits. If you're streaming the entire chain into your database, or have a very active subgraph, these savings can be considerable, and the disk performance is significantly more stable and results in more stable CPU usage pattern. + +### Supabase + +Supabase's direct connection URLs only support IPv6 connections and will not work with our default validation. There are two solutions + +1. Use `Session Pooling`. In the connection screen, scroll down to see the connection string for the session pooler. This will be included in all Supabase plans and will work for most people. However, sessions will expire, and may lead to some warning logs in your pipeline logs. These will be dealt with gracefully and no action is needed. No data will be lost due to a session disconnection. + + +2. Alternatively, buy the IPv4 add-on, if session pooling doesn't fit your needs. It can lead to more persistent direct connections, + + +--- + +> To find navigation and other pages in this documentation, fetch the llms.txt file at: https://docs.goldsky.com/llms.txt + +# ClickHouse + +[ClickHouse](https://clickhouse.com/) is a highly performant and cost-effective OLAP database that can support real-time inserts. Mirror pipelines can write subgraph or blockchain data directly into ClickHouse with full data guarantees and reorganization handling. + +Mirror can work with any ClickHouse setup, but we have several strong defaults. From our experimentation, the `ReplacingMergeTree` table engine with `append_only_mode` offers the best real-time data performance for large datasets. + +[ReplacingMergeTree](https://clickhouse.com/docs/en/engines/table-engines/mergetree-family/replacingmergetree) engine is used for all sink tables by default. If you don't want to use a ReplacingMergeTree, you can pre-create the table with any data engine you'd like. If you don't want to use a ReplacingMergeTree, you can disable `append_only_mode`. + +Full configuration details for Clickhouse sink is available in the [reference](/reference/config-file/pipeline#clickhouse) page. + +## Secrets + + + **Use HTTP** + Mirror writes to ClickHouse via the `http` interface (often port `8443`), rather than the `tcp` interface (often port `9000`). + + +```shell theme={null} + +goldsky secret create --name A_CLICKHOUSE_SECRET --value '{ + "url": "clickhouse://blah.host.com:8443?ssl=true", + "type": "clickHouse", + "username": "default", + "password": "qwerty123", + "databaseName": "myDatabase" +}' +``` + +## Required permissions + +The user will need the following permissions for the target database. + +* CREATE DATABASE permissions for that database +* INSERT, SELECT, CREATE, DROP table permissions for tables within that database + +```sql theme={null} +CREATE USER 'username' IDENTIFIED WITH password 'user_password'; + +GRANT CREATE DATABASE ON goldsky.* TO 'username'; +GRANT SELECT, INSERT, DROP, CREATE ON goldsky.* TO 'username'; +``` + +It's highly recommended to assign a ROLE to the user as well, and restrict the amount of total memory and CPU the pipeline has access to. The pipeline will take what it needs to insert as fast as possible, and while that may be desired for a backfill, in a production scenario you may want to isolate those resources. + +## Data consistency with ReplacingMergeTrees + +With `ReplacingMergeTree` tables, we can write, overwrite, and flag rows with the same primary key for deletes without actually mutating. As a result, the actual raw data in the table may contain duplicates. + +ClickHouse allows you to clean up duplicates and deletes from the table by running + +```sql theme={null} +OPTIMIZE FINAL; +``` + +which will merge rows with the same primary key into one. This may not be deterministic and fully clean all data up, so it's recommended to also add the `FINAL` keyword after the table name for queries. + +```SQL theme={null} +SELECT +FROM FINAL +``` + +This will run a clean-up process, though there may be performance considerations. + +## Append-Only Mode + + + **Proceed with Caution** + + Without `append_only_mode=true` (v2: `appendOnlyMode=true`), the pipeline may hit ClickHouse mutation flush limits. Write speed will also be slower due to mutations. + + +Append-only mode means the pipeline will only *write* and not *update* or *delete* tables. There will be no mutations, only inserts. + +This drastically increases insert speed and reduces Flush exceptions (which happen when too many mutations are queued up). + +It's highly recommended as it can help you operate a large dataset with many writes with a small ClickHouse instance. + +When `append_only_mode` (v2: `appendOnlyMode`) is `true` (default and recommended for ReplacingMergeTrees), the sink behaves the following way: + +* All updates and deletes are converted to inserts. +* `is_deleted` column is automatically added to a table. It contains `1` in case of deletes, `0` otherwise. +* If `versionColumnName` is specified, it's used as a [version number column](https://clickhouse.com/docs/en/engines/table-engines/mergetree-family/replacingmergetree#ver) for deduplication. If it's not specified, `insert_time` column is automatically added to a table. It contains insertion time and is used for deduplication. +* Primary key is used in the `ORDER BY` clause. + +This allows us to handle blockchain reorganizations natively while providing high insert speeds. + +When `append_only_mode` (v2: `appendOnlyMode`) is `false`: + +* All updates and deletes are propagated as is. +* No extra columns are added. +* Primary key is used in the `PRIMARY KEY` clause. + + +--- + +> To find navigation and other pages in this documentation, fetch the llms.txt file at: https://docs.goldsky.com/llms.txt + +# Elasticsearch + +Give your users blazing-fast auto-complete suggestions, full-text fuzzy searches, and scored recommendations based off of on-chain data. + +[Elasticsearch](https://www.elastic.co/) is the leading search datastore, used for a wide variety of usecase for billions of datapoints a day, including search, roll-up aggregations, and ultra-fast lookups on text data. + +Goldsky supports real-time insertion into Elasticsearch, with event data updating in Elasticsearch indexes as soon as it gets finalized on-chain. + +See the [Elasticsearch docs](https://www.elastic.co/guide/en/elasticsearch/reference/7.17/elasticsearch-intro.html) to see more of what it can do! + +Full configuration details for Elasticsearch sink is available in the [reference](/reference/config-file/pipeline#elasticsearch) page. + +Contact us at [sales@goldsky.com](mailto:sales@goldsky.com) to learn more about how we can power search for your on-chain data! + +## Secrets + +Create an Elasticsearch secret with the following CLI command: + +```shell theme={null} +goldsky secret create --name AN_ELASTICSEARCH_SECRET --value '{ + "host": "Type.String()", + "username": "Type.String()", + "password": "Type.String()", + "type": "elasticsearch" +}' +``` + + +--- + +> To find navigation and other pages in this documentation, fetch the llms.txt file at: https://docs.goldsky.com/llms.txt + +# Timescale + + + **Closed Beta** + + This feature is in closed beta and only available for our enterprise customers. + + Please contact us at [support@goldsky.com](mailto:support@goldsky.com) to request access to this feature. + + +We partner with [Timescale](https://www.timescale.com) to provide teams with real-time data access on on-chain data, using a database powerful enough for time series analytical queries and fast enough for transactional workloads like APIs. + +Timescale support is in the form of hypertables - any dataset that has a `timestamp`-like field can be used to create a Timescale hypertable. + +You can also use the traditional JDBC/postgres sink with Timecale - you would just need to create the hypertable yourself. + +You use TimescaleDB for anything you would use PostgreSQL for, including directly serving APIs and other simple indexed table look-ups.

Set Environment Variable + +```env +NEXT_PUBLIC_CREATOR_IP_FACTORY_ADDRESS=0x... +``` + +### 3. Deploy Collection for Creator + +```typescript +import { deployCreatorCollection } from "@/lib/sdk/story/factory-contract-service"; +import { useSmartAccountClient } from "@account-kit/react"; +import type { Address } from "viem"; + +function CreateCollectionButton({ creatorAddress }: { creatorAddress: Address }) { + const { client } = useSmartAccountClient({}); + + const handleDeploy = async () => { + if (!client) { + console.error("Smart account client not available"); + return; + } + + const result = await deployCreatorCollection( + client, + creatorAddress, + "Creator Name's Videos", + "CRTV" + ); + + console.log("Collection deployed:", result.collectionAddress); + }; + + return ; +} +``` + +## Delegate Functionality (AI Agent Minting) + +### Granting Minter Role to Platform + +Creators can grant the platform (AI agents) permission to mint on their behalf: + +```typescript +import { grantPlatformMinterRole } from "@/lib/sdk/story/factory-contract-service"; + +// Creator calls this to allow platform to mint +const result = await grantPlatformMinterRole( + creatorSmartAccountClient, // Must be creator's account + collectionAddress, + platformMinterAddress +);

+``` + +### Revoking Minter Role + +Creators can revoke platform access anytime: + +```typescript +// In CreatorIPCollection contract +function revokeMinterRole(address minter) external onlyOwner { + _revokeRole(MINTER_ROLE, minter); +} +``` + +## Batching with Alchemy Account Kit + +You can batch collection deployment + first mint in a single User Operation using Account Kit's batching capabilities: + +```typescript +import { useSmartAccountClient } from "@account-kit/react"; + +const { client } = useSmartAccountClient({}); + +// Batch: Deploy collection + mint first NFT +const batch = [ + { + target: factoryAddress, + data: deployCollectionData, + value: 0n, + }, + { + target: collectionAddress, // From first operation + data: mintData, + value: 0n, + }, +];
