Chapter 4. Moxi with Memcached

Moxi speaks the memcached protocol, so it can work with both memcached servers and Membase servers.

When used with Membase, Moxi is started with a REST/URL that describes the Membase cluster configuration, and Moxi uses vbucket hashing to determine which key-value items live on which servers.

When used with standard, classic memcached, Moxi should be started with different command-line parameters that will make Moxi use libmemcached (ketama) hashing. In particular, Moxi will take a different cluster or -z command-line flag, like...

./moxi -z LISTEN_PORT=MEMCACHED_HOST1[:PORT1][,MEMCACHED_HOSTN[:PORTN]]

The memcached PORT's default to 11211. For example, below, moxi will listen on port 11811 and use ketama hashing against a server-list of mc1:11211,mc2:11211:

./moxi -z 11811=mc1,mc2
              ./moxi -z 11811=mc1:11211,mc2:11211

You may also move the -z cluster configuration into a separate file, by specifying either an absolute or relative path...

./moxi -z ./relative/path/to/cluster/config_file
              ./moxi -z /absolute/path/to/cluster/config_file

The contents of the config_file should look like...

11811=mc1:11211,mc2:11211
