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.

http://code.google.com/p/memcache-client-forjava/ is another choice

shouldn't the PHP PECL/memcache section call it the "php memcache docs" instead of "php memcached docs" ?

"Cold Fusion" should be ColdFusion?. Please... :)

Comment by rsand...@gmail.com, Sep 25, 2009

I'm writing a Z-Shell (ZSH) interface as part of a ZSH framework called "dotto". Most operations work. Like git, there's plumbing and porcelain; the plumbing's mostly done except for multiple servers. The porcelain is in progress. Also, not much in the way of docs yet.

You can get it here:

Starting on a rebol client: http://babelserver.org/rebol/memcached/

All comments are welcome.

Comment by omnifari...@gmail.com, Oct 18, 2009

python-memcached has a broken link. The working link is: http://www.tummy.com/Community/software/python-memcached/

Comment by manifest...@gmail.com, Dec 4, 2009

Good PHP Memcached Class: http://code.google.com/p/memcachemanager/

Supports key tagging and has great documentation. Class also generates memory usages reports, which have come in very handy.

This page has been particularly helpful as it covers in plain English what all the memcached variables mean, and what they do.

pylibmc is the best python memcached library: http://pypi.python.org/pypi/pylibmc

Please update the Chicken link to point at http://wiki.call-cc.org/eggref/3/memcached - it hasn't been ported to Chicken 4 yet.

Hi, The Enyim Memcache client for .NET is now here: http://memcached.enyim.com/

Comment by bjornsm...@gmail.com, Sep 26, 2010

Another memcached client is available here:

http://asyncmemcached.codeplex.com

As the name kind of hints its fully asynchronous.

Comment by abraka...@gmail.com, Nov 10, 2010

The C/C++ libmemcached link is broken for me, try http://libmemcached.org/libMemcached.html.

Comment by huangxia...@gmail.com, Dec 13, 2010

I can't access the libmemcached link either, and I think it's obsolete.

Comment by nathan.l...@gmail.com, Dec 24, 2010

The MySQL links appear to be broken as well. Otherwise this is a great resource

Comment by mper...@gmail.com, Aug 23, 2011

The Ruby clients are far out of date. As of 2011, there are two mainstream supported clients:

memcached - https://github.com/fauna/memcached (wraps libmemcached)
dalli - https://github.com/mperham/dalli (pure Ruby)

Comment by paga...@gmail.com, Sep 8, 2011

NMemcached.Client is available at http://nmemcached.codeplex.com/. It has both text and binary protocol support, TCP connections for both protocols, UDP connections for the binary protocol, synchronous and asynchronous client classes, and dead server detection.
