Memory Management Patterns

Comprehensive patterns for managing memory, state, and context in Claude Code sessions, with special focus on long-running sessions and persistent memory strategies.

📚 Available Patterns

Core Patterns

  • Long-Running Sessions - Strategies for extended Claude Code sessions
  • State Persistence - Saving and restoring session state
  • Memory Optimization - Efficient memory usage patterns
  • Context Recycling - Reusing context across sessions

🎯 Key Management Areas

1. Session Memory Management

  • Context window optimization
  • State tracking
  • Memory limits handling
  • Garbage collection strategies

2. Persistent Memory

  • Session state saving
  • Cross-session memory
  • Knowledge persistence
  • Context restoration

3. Memory Optimization

  • Selective loading
  • Context compression
  • Smart eviction
  • Priority management

4. Long-Running Operations

  • Memory leak prevention
  • State checkpointing
  • Incremental processing
  • Resource monitoring

🔧 Memory Management Strategies

Session State Management

interface SessionMemory {
  // Core session data
  context: ContextWindow
  state: SessionState
  history: CommandHistory
  
  // Memory operations
  save(): Promise<void>
  restore(sessionId: string): Promise<void>
  optimize(): void
  clear(): void
}

Memory Optimization Patterns

optimization_strategies:
  compression:
    - summarize_old_context
    - remove_redundant_info
    - compress_large_files
  
  eviction:
    - lru_cache
    - priority_based
    - time_based
  
  persistence:
    - checkpoint_regularly
    - save_critical_state
    - export_knowledge

💡 Best Practices

1. Efficient Memory Usage

  • Monitor memory consumption
  • Clear unused context
  • Use references over content
  • Implement smart caching

2. State Management

  • Regular checkpointing
  • Atomic state updates
  • Versioned snapshots
  • Quick recovery

3. Long Session Handling

  • Periodic optimization
  • Memory leak detection
  • Resource monitoring
  • Graceful degradation

4. Knowledge Persistence

  • Extract key insights
  • Build knowledge base
  • Cross-session learning
  • Pattern recognition

🚀 Advanced Techniques

Intelligent Memory Management

class MemoryManager {
  // Adaptive memory allocation
  async allocate(requirement: MemoryRequirement) {
    if (this.available < requirement.size) {
      await this.evict(requirement.priority)
    }
    return this.reserve(requirement)
  }
  
  // Smart eviction
  async evict(minPriority: number) {
    const candidates = this.getEvictionCandidates(minPriority)
    for (const item of candidates) {
      if (this.available >= this.target) break
      await this.remove(item)
    }
  }
}

Session Continuity

// Save session state
async function saveSession(session: Session) {
  const state = {
    context: session.getContext(),
    memory: session.getMemory(),
    history: session.getHistory(),
    timestamp: Date.now()
  }
  await storage.save(session.id, state)
}
 
// Restore session
async function restoreSession(sessionId: string) {
  const state = await storage.load(sessionId)
  const session = new Session()
  session.restore(state)
  return session
}

📋 Implementation Patterns

1. Checkpoint Pattern

Regular state saving for recovery:

// Automatic checkpointing
setInterval(async () => {
  await session.checkpoint()
}, CHECKPOINT_INTERVAL)
 
// Manual checkpoint before risky operations
await session.checkpoint()
await performRiskyOperation()

2. Memory Pool Pattern

Pre-allocated memory management:

class MemoryPool {
  private pool: MemoryBlock[]
  
  async acquire(size: number): Promise<MemoryBlock> {
    const block = this.pool.find(b => b.size >= size)
    if (!block) {
      await this.expand()
      return this.acquire(size)
    }
    return block
  }
}

3. Context Window Sliding

Maintain relevant context efficiently:

class SlidingContext {
  private window: ContextItem[]
  private maxSize: number
  
  add(item: ContextItem) {
    this.window.push(item)
    while (this.size > this.maxSize) {
      this.evictOldest()
    }
  }
}
