UncleBig/goCache — An in-memory key:value store/cache similar to memcached that is suitable for applications running on a single machine. Any object can be stored, for a given duration or forever, and the cache can be safely used by multiple goroutines.
foocsim — Simple file or object cache simulator
go-leveldb-objectstorage — readonly wrapper for leveldb saved in object storage with cache for golang
marcojetson/kv — In memory object cache
