Persistent message queues memcacheq .memcacheq describes a mounting configuration features: 1. Easy to use processing speed 2. 3. 4. A plurality of queue concurrent performance compatible 5. 6. Good use conveniently zend framework memcacheq in agreement with memcache rely on Berkeley DB and libevent. Berkeley DB queue for persistent storage of data, to avoid memcacheq this server crash or crash when the data will not be lost.
