For original README, see README.orig = About = Building on merle and ketama, this application enables memcached access from erlang. = Prerequisites = - ruby and rake for building - libketama <http://www.audioscrobbler.net/development/ketama/> - memcached servers <http://www.danga.com/memcached/> = Builing = Run rake a first time and make sure ERL_TOP is set at the right location. sudo rake install will install the application where necessary. = Example Usage = Provide a ketama.servers file (such as the one here). Open 3 terminals and start memcached in each one of them on a different port : $ memcached -p 11211 -vv $ memcached -p 11212 -vv $ memcached -p 11213 -vv Open another terminal, and run : $ erl -s merle -merle file '"ketama.servers"' # use the one included here. You should see on the memcached servers something like : <18 new client connection For the rest, see the README.orig file You should see that the keys you set are distributed amongs the servers. = Editing the ketama file = The ketama.servers file is tracked and reloaded each time it is modified. ketama provided consistent hashing goodness ; adding and removing memcached servers does not invalidate all the cache. One caveat : currently the app doesn't flush newly added memcached servers, that may cause inconsistencies. On top of that, I have not implemented the flush command for a specific server. = Authors = Eric Cestari, maintaining this stuff.
