Rhizome-Node Repository Analysis

Core Architecture

1. Delta System

  • Delta Types: Implements V1 (array-based) and V2 (object-based) delta formats
  • Delta Lifecycle:
    • Creation via DeltaBuilder
    • Propagation through DeltaStream
    • Storage in Lossless view
    • Transformation in Lossy views

2. Network Layer

  • Communication:
    • Pub/Sub system for delta propagation
    • Request/Reply pattern for direct communication
    • Peer management
  • Delta Propagation:
    • Deduplication using content hashing
    • Policy-based acceptance/rejection
    • Queuing for deferred processing

3. Storage

  • In-Memory Storage:
    • Lossless view maintains complete delta history
    • Lossy views provide optimized access patterns
  • Persistence:
    • LevelDB integration
    • Delta compaction strategies

4. Schema System

  • Type Definitions:
    • Support for primitives, references, and arrays
    • Validation rules
  • Schema Registry:
    • Central schema management
    • Versioning support

Key Components

  1. Core:

    • delta.ts: Core delta implementation
    • delta-builder.ts: Fluent API for delta creation
    • entity.ts: Base entity definitions
  2. Network:

    • delta-stream.ts: Delta propagation and management
    • pub-sub.ts: Publish/subscribe functionality
    • request-reply.ts: Direct node communication
  3. Views:

    • lossless.ts: Complete delta history
    • lossy.ts: Derived, optimized views
  4. Schema:

    • schema.ts: Type definitions
    • schema-registry.ts: Schema management

Strengths

  1. Flexible Data Model: Hypergraph structure supports complex relationships
  2. Extensible: Plugin architecture for storage and networking
  3. Type Safety: Comprehensive TypeScript types
  4. Incremental Processing: Efficient updates with Lossy views

Areas for Improvement

    • Sharding support
  4. Security:

    • Authentication/authorization
    • Delta signing/verification
    • Encryption
