CLI
libmemcached
- http://libmemcached.org/ by Brian Aker, Commercial Support available from Data Differential
- BSD licensed, contains a full set of CLI tools.
Protocol
To write a new client, check out the binary protocol docs and ascii protocol docs. Be aware that the most important part of the client is the hashing across multiple servers, based on the key, or an optional caller-provided hashing value. Feel free to join the mailing list for help and/or a link to your client from this site.
