Yes, and a very, very fast one too ... like, 120,000 operations per second. PostgreSQL can't match that because of the overhead of authentication, security, transaction visibility checking, etc. So memcached becomes a very good place to stick data that's read often but not updated often, or alternately data that changes often but is disposable. An example of the former is a user+ACL list; and example of the latter is web session information ... or simple materialized views. -- Josh Berkus Aglio Database Solutions San Francisco ---------------------------(end of broadcast)--------------------------- TIP 7: don't forget to increase your free space map settings
