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.
