Mix-master

A Deterministic State Aggregation and Synthesis Engine for Heterogeneous Data Pipelines.

Status License Contribution Version

1. Project Overview and Scope Mix-master is engineered to solve the N-source data synthesis problem in partitioned distributed environments. Its core mandate is to ingest disparate, potentially conflicting configuration fragments or data streams and produce a singular, canonical, and deterministically reconciled output state.

This project is built on the principles of strong eventual consistency and relies on an underlying algebra for idempotent state merging, abstracting away the complexities of fault-tolerant state aggregation from consuming services.

Key Capabilities Idempotent Aggregation: Guarantees that re-running the synthesis process yields the identical output for the same input set, irrespective of processing order or repetition.

Conflict Resolution (Explicit): Utilizes user-defined conflict resolution strategies (CRSs) at the merge layer instead of opaque heuristics.

Declarative State Definition: Accepts input states (fragments) via a structured IDL (e.g., JSON Schema, Protocol Buffers) to enforce rigor at the boundary.

2. Conceptual Architecture (State Transition Model) The Mix-master engine operates as a pipeline of functional transformations, driven by an external change event stream.

2.1. Component Hierarchy Component Function Concurrency Strategy Consistency Requirement Ingress Layer Consumption of fragmented state updates (e.g., Kafka, Message Bus, S3 PUT). Lock-Free Queuing (MPSC) Temporal Ordering (Weak) Reconciliation Kernel The core state machine. Applies user-defined merge rules. Read-Copy-Update (RCU) or Optimistic Locking (dependent on I/O) Strong Eventual Consistency (SEC) via CRDT/Merge Algebra Output Egress Publication of the canonical, synthesized state. Wait-Free (Non-blocking I/O) Atomicity (Publish single, complete state) 2.2. State Merge Algebra The core operation is the F merge

function, which is required to be:

S final

=F merge

(S A

,S B

,…,S N

) Where S i

are input fragments, and S final

is the canonical state.

To enforce determinism, the system relies on a Mergeable Data Type (MDT), which is an abstract equivalent of a Conflict-free Replicated Data Type (CRDT), ensuring that concurrent updates commute and associative laws hold across the fragment application sequence. The specific CRDT type utilized will depend on the data structure being synthesized (e.g., Last-Write-Wins Register, G-Set, or 2P-Set).

3. Technology Stack & Prerequisites This project targets a high-performance execution environment suitable for mission-critical configuration management.

Element Specification Rationale Language [PLACEHOLDER: Rust / Go / C++] Prioritizes low-latency execution and memory safety/concurrency primitives. Dependencies [PLACEHOLDER: list libraries, e.g., Serde for Rust, Go-CRDT library, etc.] Required for efficient serialization, deserialization, and algebraic operations. Build System [PLACEHOLDER: Cargo / Bazel / Make] Ensures reproducible, hermetic builds for production deployment. 4. Installation and Local Setup The following steps outline the procedure for cloning, building, and executing the synthesis engine.

4.1. Prerequisites Ensure the target system has the required toolchain installed:

Bash

Example: Placeholder for language-specific toolchain

$ [PLACEHOLDER: Install Build Toolchain] 4.2. Clone and Build Bash $ git clone https://github.com/Lukesworld/Mix-master.git $ cd Mix-master

Execute the specific build command for artifact generation

$ [PLACEHOLDER: Build Command, e.g., cargo build --release] 4.3. Execution (CLI Mode) To validate the synthesis kernel, use the provided CLI (Command Line Interface) entry point:

Bash

Example: Synthesize state from a directory of fragments

$ ./mix-master --mode synthesize --input-dir /etc/fragments/ --output-path /tmp/canonical.json

Example: Run in Daemon mode to listen for message queue events

$ ./mix-master --mode daemon --config /etc/mixmaster/runtime.toml 5. Contribution & Extensibility Contributions are welcomed, particularly in extending the core CRDT implementations and designing new, provably correct F merge

strategies.
