cache

Motivation

​ Sometimes we need a cache library binding our service, so that to reach a target which once our service dead, cache data is invalid too or not exist.

​ There are some cache in the market, like as redis, memcache, groupcache and so on. certainly the other embed key value database , like as boltdb, rocksdb, leveldb, etc. they aren't satisfy with the below features.

​ So I create this new cache, welcome to use.

if it can help you, please star this repository, thanks

Features

• ​ No need for persistent caching
• ​ Support range query based on key value
• ​ Performance represents not bad
• ​ As part of the service
