Cascade Disabled Cache Invalidation Logic

Users see stale cached data after Cascade refactored cache management. Data is updated in database but cached version isn't invalidated, so users continue seeing old information until cache expires naturally (after hours or days).

Cascade likely removed @CacheEvict annotations or cache clearing logic.

Error Messages You Might See

Stale data served from cache Cache not invalidated after update Users see outdated information
Stale data served from cacheCache not invalidated after updateUsers see outdated information

Common Causes

  1. Cascade removed @CacheEvict or @CacheEvict methods during refactoring
  2. Cache key structure changed without updating eviction logic
  3. Cascade removed cache invalidation from update/delete operations
  4. Cascade removed RedisCache invalidation after data mutations

How to Fix It

Add @CacheEvict to methods that modify data (save, update, delete). Specify cache names and keys. Use allEntries=true to clear entire cache if needed. Test that reading modified data returns fresh data. Use Redis CLI to verify cache is being cleared: KEYS * to see cache keys, DEL to clear.
