Part of Issue #62 - Agent Memory System

Phase: 4 (Integration)
Priority: P2
Complexity: Medium

Overview

Implement caching for memory operations to improve performance.

Features

  • Hot memory caching (frequently accessed memories)
  • Retrieval result caching
  • Embedding caching (avoid recomputing)
  • Cache invalidation strategies

Caching Strategy

  1. Hot Memory Cache: LRU cache for frequently accessed memories
  2. Retrieval Cache: Cache search results by query hash
  3. Embedding Cache: Cache embeddings by content hash
  4. Invalidation: TTL-based + explicit invalidation on updates

Performance Targets

  • Cache hit rate > 80% for hot memories
  • Retrieval speedup > 10x for cached queries

Acceptance Criteria

  • All caching layers implemented
  • Invalidation working correctly
  • >90% test coverage
  • make validate-all passes
  • Multi-agent review completed
