The cache layer has race conditions between check_connection(), TTL expiry, and concurrent access patterns. InMemory cache's expiry check is not atomic with retrieval.
Current Issues
get_raw_with_expiry() not atomic - entry could expire between check and return- Multiple tasks could initialize Redis connection simultaneously
- No cache invalidation strategy for stale entries
- Metrics not protected against concurrent updates
RedisCache doesn't validate connection state before operations
Required Changes
- Implement atomic operations for expiry checks using
AtomicU64
- Add connection pooling and health checks with backoff
- Create cache invalidation policy (LRU, TTL-based, event-driven)
- Add mutex protection for shared metrics state
- Implement cache warming strategies for critical data
- Add comprehensive integration tests for concurrent access
Acceptance Criteria
- No data races detected under concurrent load testing
- Cache consistency maintained across all backends
- Metrics accurate under high concurrency
- Clear documentation of cache guarantees
