wcache

Implements in-memory cache with write-back strategy (a cache with expiration). An expiration callback(expireFn) will be called when record is expired.

Features

• Thread-safe.
• Per-key or global TTL.
• Can trigger a custom callback on key expiration(could be used as Pub/Sub with aggregation).
• Can trigger a custom callback on key collisions(e.g. for aggregating metrics). By default, will overwrite value.
• Graceful shutdown(using context). Will call expiration callback for all records, ignoring they TTL.

Install

go get github.com/vtopc/wcache

TODO

• Optional auto-extending expiration on Get and/or Set.
