CoCacheLevel 2 Distributed Coherence Cache

A high-performance, two-level caching framework for Java/Kotlin with automatic cache coherence via event bus.

Two-Level Caching

L2 (local in-memory via Guava/Caffeine) + L1 (distributed via Redis) with automatic cache promotion and write-through to both tiers.

CacheEvictedEventBus enables distributed cache invalidation across all instances via Redis Pub/Sub or in-process event bus.

Declarative cache configuration with @CoCache, @GuavaCache, @CaffeineCache, and @JoinCacheable annotations.

Fine-grained per-key locking with double-check pattern prevents thundering herd on cache misses.

Automatic TTL randomization prevents cache avalanche when multiple entries expire simultaneously.

Compose multiple cached values into a single result with cross-cache join semantics and automatic invalidation.
