MemcacheDB is a distributed key-value storage system designed for persistent. It is NOT a cache solution, but a persistent storage engine for fast and reliable key-value based object storage and retrieval. It conforms to memcache protocol(not completed, see below), so any memcached client can have connectivity with it. MemcacheDB uses Berkeley DB as a storing backend, so lots of features including transaction and replication are supported.
We stand on the shoulders of giants, MemcacheDB source code is based on Memcached.
MemcacheQ is a MemcacheDB variant that provides a simple message queue service.

- High performance read/write for a key-value based object
- High reliable persistent storage with transcation
- High availability data storage with replication
- Memcache protocol compatibility
MemcacheDB is very fast. See our Benchmark.
MemcacheDB is compatible with memcache protocol, so any clients that support memcache protocol have connectivity with it.
But take a look at the commands now MemcacheDB supports:
Client APIs that supports memcache protocol can be found here.
- get(also mutiple get)
- set, add, replace

Also some private commands are supported:
