When deploying to serverless environments, prefer short-lived transactions with explicit pooling to avoid exhausting limits. +- **Schema contracts:** Validate each Actor item against the target table schema before insert. Run migrations (SQL files, Supabase `supabase db pull/push`, Prisma migrate) as a separate step, never inline with the data load. +- **Batch & upsert:** Insert in batches sized to the database’s parameter limit (e.g., 500–1000 rows for Postgres). Use COPY/`INSERT ... ON CONFLICT`/`UPSERT` semantics to deduplicate on unique keys or hashed payloads. +- **Idempotency:** Include a deterministic primary key (URL, external ID, hash) per record so replays replace data rather than duplicating it. Log the Actor run ID alongside each batch for traceability. +- **Observability:** Emit metrics for rows inserted, skipped, and failed. Store links to the Apify dataset or Actor run to aid debugging. +- **Error handling:** Wrap writes in transactions and retry transient failures with exponential backoff. Abort and alert on migration conflicts instead of guessing how to recover. -## 5.

'No title'; - const points = item.points ?? 0; +- **Embedding pipeline:** Ensure the embedding model used during ingestion matches the index configuration (dimension, metric). Chunk long documents before embedding just like the Apify→Pinecone example in the docs. +- **Namespaces & multitenancy:** Use namespaces (Pinecone) or collections (Qdrant/Milvus) to isolate tenants or data domains. Reuse gRPC/HTTP connections across namespaces when supported. +- **Batch upserts:** Send vectors in batches sized to the provider’s limit (e.g., 100 vectors). Include metadata (source URL, timestamp, schema version) to power filtered queries later. +- **Deduplication:** Derive vector IDs from stable fields (e.g., `hash(url + sectionId)`) so updated content replaces stale vectors automatically. Enable delta/deletion logic (Apify Pinecone integration’s `enableDeltaUpdates`, `deleteExpiredObjects`) when available. +- **Index lifecycle:** Document how to rotate models or rebuild indexes. Prefer blue/green deployments: backfill a new index, switch queries, then decommission the old one. +- **Security:** Store Pinecone/Qdrant API keys in secrets stores, not code. Grant least-privilege access (read vs write tokens) per environment. - console.log(`${index + 1}. ${title}`); - console.log(` URL: ${url}`); - console.log(` Points: ${points}`); -}); -``` +## Integration checklist +Use this lightweight checklist to catch common edge cases before handing work back to the user: -# Run Any Apify Actor in Python +- ✅ **Environment & secrets**: Confirm `APIFY_TOKEN` and other credentials are documented, validated at runtime, and never committed to version control. +- ✅ **Framework constraints**: Note any asset allowlists, execution timeouts, cold-start limits, CSP/CORS policies, or SSR restrictions and adapt the integration accordingly. +- ✅ **Data normalization**: Ensure Actor outputs are typed, sanitized, and have explicit defaults for missing or malformed fields (e.g., prices as strings, null descriptions). +- ✅ **Pagination & scale**: Plan for large result sets; prefer paginated dataset fetches and avoid loading thousands of items at once. +- ✅ **External asset hygiene**: Validate that images, files, or media URLs from Actor results comply with framework restrictions (e.g., `next/image` allowlists). Provide fallback renderers or placeholders when assets are blocked. +- ✅ **Idempotency & deduplication**: Handle scenarios where the same Actor run is triggered multiple times or returns duplicate items. +- ✅ **Error surfacing**: Display user-friendly error messages when Actors fail, time out, or return empty datasets. Surface Actor run IDs and console links for debugging. +- ✅ **Timeouts & retries**: Implement sensible timeouts for `waitForFinish()` and retry logic for transient failures (with exponential backoff). +- ✅ **Budget awareness**: Highlight usage costs, especially for expensive Actors or high-frequency runs. Link to Apify pricing/usage dashboards. +- ✅ **Observability**: Log Actor run IDs, execution times, and dataset sizes. Provide links to the Apify Console for each run so users can inspect results and debug issues. +- ✅ **Testing coverage**: Outline manual or automated tests (including Playwright E2E if applicable) that prove the Actor workflow succeeds and failure states are handled gracefully. +- ✅ **Maintenance tasks**: Highlight post-integration responsibilities such as monitoring Actor runs, quota usage, updating Actor versions, and adjusting input schemas as APIs evolve. +- ✅ **Database hygiene**: Confirm connection pooling, batching, schema migrations, and upsert/dedup strategies are reviewed before shipping. Document rollback steps if a batch fails midway. +- ✅ **Vector index health**: Track embedding model versions, index namespaces, and deletion policies so RAG or semantic-search consumers can trust the dataset. ---- +## Apify best practices -## 1. Install Apify SDK +### Secrets & environment Setup -```bash -pip install apify-client -``` +- Store `APIFY_TOKEN` in `.env` or `.env.local` (gitignored). Direct users to create tokens at https://console.apify.com/account#/integrations. +- For server-side integrations (API routes, backend services), keep tokens server-only to avoid exposing them to client bundles. +- For client-side calls (rare), use `NEXT_PUBLIC_APIFY_TOKEN` or equivalent public env vars, but prefer server-side proxies for production. +- Store database credentials (`DATABASE_URL`, Supabase service role keys, Pinecone API keys) in GitHub Actions/Repo Secrets or your hosting platform’s secret manager. Reference them via environment variables inside Copilot agent instructions per [GitHub’s custom agent guidance](https://docs.github.com/en/copilot/concepts/agents/coding-agent/about-custom-agents). +- When the agent needs to read/write databases through MCP, grant only the minimal set of tools (e.g., read-only SQL for analysis, dedicated mutation endpoints for ingestion). ---- +### Actor run lifecycle -## 2. Set up Client (with API token) +- **Start an Actor**: Use `client.actor(actorId).call(input)` to initiate a run. This returns a run object with `id` and `defaultDatasetId`. +- **Wait for completion**: Call `client.run(runId).waitForFinish()` to poll until the run finishes. Set a reasonable timeout (e.g., 5 minutes for scraping, 30 seconds for simple tasks). +- **Check status**: After waiting, inspect `run.status` to distinguish `SUCCEEDED`, `FAILED`, `TIMED-OUT`, and `ABORTED`. Handle each case appropriately. +- **Surface run links**: Log or display the run URL (`https://console.apify.com/actors/runs/{runId}`) so users can inspect logs, dataset previews, and error traces in the Apify Console. -```python -from apify_client import ApifyClient -import os +### Dataset access & pagination -client = ApifyClient(os.getenv("APIFY_TOKEN")) -``` +- **Fetch items**: Use `client.dataset(datasetId).listItems()` to retrieve results. For large datasets, paginate with `offset` and `limit` parameters. +- **Field selection**: If the Actor returns many fields but you only need a few, consider filtering fields client-side or using dataset views/transformations (if supported by the Actor). +- **Empty results**: Always handle the case where `items` is an empty array (Actor ran successfully but found no data). ---- +### Rate limits, concurrency & proxies -## 3. Run an Actor +- **Rate limits**: Apify enforces platform limits on API calls and concurrent Actor runs. Start with sequential runs and scale gradually. +- **Concurrency**: If running multiple Actors in parallel, monitor your account's concurrency limits and queue runs appropriately. +- **Proxies**: Many Actors use Apify Proxy or custom proxies to avoid IP bans. Check Actor documentation for proxy configuration options (e.g., residential proxies for e-commerce). -```python -# Run the official Web Scraper -actor_call = client.actor("apify/web-scraper").call( - run_input={ - "startUrls": [{"url": "https://news.ycombinator.com"}], - "maxDepth": 1, - } -) +### Cost & budget management -print(f"Actor started! Run ID: {actor_call['id']}") -print(f"View in console: https://console.apify.com/actors/runs/{actor_call['id']}") -``` +- **Understand pricing**: Actors consume compute units (CUs) based on memory and runtime. Review Actor pricing on its Store page. +- **Set budgets**: Use Apify's usage alerts and limits to avoid unexpected costs during development. +- **Optimize runs**: Minimize runtime by tuning Actor inputs (e.g., reduce `maxPages`, narrow search queries). ---- +## Official SDK references -## 4.
