Jemcache is a java implementation of a Memcached server. It's primary purpose is for embedding in unit tests. The performance actually is quite good, however, it does not scale as well as the c version of Memcached.

All of the APIs are implemented as defined in the protocol documentation except for UDP and timed deletes. The near-term roadmap is to implement the missing features in the following order: timed deletes, UDP.

Launch Jemcache

###Standalone server

java -jar jemcache.jar [port [memory-in-mb]]

###Nio implementation

java -classpath jemcache.jar org.jemcache.server.JemcacheNioServer [port [memory-in-mb [num-threads]]]

Embed Jemcache

JemcacheServer jemcacheServer = new JemcacheServer(port, memoryLimitBytes); ###or JemcacheNioServer jemcacheNioServer = new JemcacheNioServer(port, memoryLimitBytes, numThreads);
