Projects / jmemcached


jmemcached is a fast network available cache daemon. It is protocol-compatible with memcached, but written in Java and suitable for applications with portability concerns, where Java is the preferred solution, or for using the memcached protocol in embedded applications with alternate storage engines. Existing clients for memcache work unmodified. It can run as a standalone daemon or be embedded inside an existing Java application.

          Release Notes: This release adds support for a memory-mapped heap that is external to the JVM, to allow for much larger caches and to avoid memory impact on the main JVM. It has some performance and protocol compliance improvements. It has better command line options for specifying heap and ceiling sizes. It adds a battery of unit tests.
