Phase 2: Connection Pooling & State Caching

[jessfortemnaturae8717]

Overview

Migrate to AWS SDK v3 with connection pooling and add Redis-backed state cache.

Target: 200-500ms state lookups → <50ms (70% cache hit rate)

Tasks

2.1 AWS SDK v3 Migration

• Migrate to @aws-sdk/client-* packages
• Enable HTTP/2 multiplexing
• Configure keep-alive connection pooling
• Add retry with exponential backoff

Files:

• src/state/aws/*.ts

2.2 State Cache Layer

• Add ioredis dependency
• Implement cache-aside pattern
• Add cache hit/miss metrics
• Support cache invalidation via MCP tool

New files:

• src/cache/state-cache.ts
• src/cache/redis-client.ts

Cache TTLs:

Resource	TTL
S3 bucket	60s
RDS instance	30s
EC2 instance	30s
IAM role	300s

2.3 GCP/Azure Parity

• Apply same optimizations to other cloud providers

Dependencies

ioredis: ^5.3.0
@aws-sdk/client-s3: ^3.500.0
@aws-sdk/client-rds: ^3.500.0
@aws-sdk/client-ec2: ^3.500.0

Timeline

Week 2-3
