The cache wraps the base database interface with a cache layer (decorator pattern) to improve read performance and reduce database I/O.

The cache is **optional and disabled by default**. Existing code using `NewDatabase()` continues to work without modification. + +To enable caching, use the new builder pattern: +```go +// With cache enabled +db, err := database.NewDatabaseBuilder[MyEntity](ctx, "mydb"). + WithCache(cache.CacheConfig{ + Enabled: true, + DefaultTTL: 5 * time.Minute, + CleanupInterval: 1 * time.Minute, + }). + Build() + +// Without cache (backwards compatible) +db, err := database.NewDatabase[MyEntity](ctx, "mydb") +``` + +Or enable via configuration file: +```yaml +config: + cache: + enabled: true + default_ttl: "5m" + cleanup_interval: "1m" +``` + +## Checklist +- [x] Code follows Clean Architecture principles +- [x] Code follows project style guidelines +- [x] Self-review completed +- [x] Comments added for complex logic +- [ ] All documentation updated in `./docs/` folder +- [ ] Tests pass locally (`make test`) +- [ ] Coverage requirements met (`make test-coverage`) +- [ ] No linting errors (`make lint`) +- [ ] Security scan passes (`make security`) +- [x] Branch name follows convention (enhancement/*, feature/*, fix/*, hotfix/*, release/*) + +## Screenshots/Logs (if applicable) + +### Test

when not used +- **Thread-safe**: Uses `go-cache` library which is thread-safe by design +- **Automatic invalidation**: Cache cleared on Create/Update/Delete +- **TTL support**: Entries expire after configured duration +- **go-cache library**: Uses `github.com/patrickmn/go-cache` as specified in issue #59 + diff --git a/go.mod b/go.mod index 5b4ce60..e96bb04 100644 --- a/go.mod +++ b/go.mod @@
