What problem does it solve?

ElastiCache Redis connections are frequently created per invocation, leading to latency, cold starts, and connection churn. This Skill introduces a reusable Redis client and tenant-scoped sessions combined with a cache-aside layer to improve performance and data isolation across Lambda-based microservices.

Core Features & Use Cases

• Reusable Redis client across Lambda invocations to reduce connection overhead and warm-start costs.
• Tenant-isolated SessionService to prevent cross-tenant data leakage and track user context.
• CacheService with a namespace-based cache, TTLs, and cache-aside pattern to accelerate reads and simplify data synchronization.
• Use Case: Attach to existing services created with create-lambda-service to add fast in-process caching and robust session management.

Quick Start

Integrate the provided Redis client, session service, and cache service into your existing Lambda microservice to enable tenant-isolated sessions and cache-aside caching.
