Hi,Actually, pecl/memcache version 3.0.0+ already has support for client side replication where the client writes keys to N (user specified) servers in parallel, the replicas are then used if the primary copy is unavailable. This method isn't really 100% reliably though (please use a database for that), it's more for caching data like sessions or other stuff that you'd rather not loose or have get inconsistent but it isn't totally catastrophic if you in some very infrequent cases do.
Replication can be enabled by setting either of the INI settings
# For 2 server general redundancy
memcache.redundancy = 2
# For 2 server session redundancy
memcache.session_redundancy = 2
Or like
<?php
$prev = ini_get('memcache.redundancy');
ini_set('memcache.redundancy', 2);
$redundantpool = new MemcachePool();
$redundantpool->addServer(..);
$redundantpool->addServer(..);
...
ini_set('memcache.redundancy', $prev);

Once I have them stabilized I am assuming the perl/python/php/ruby drivers will come along for the ride.Cheers, -Brian -- _______________________________________________________ Brian "Krow" Aker, brian at tangent.org Seattle, Washington http://krow.net/ <-- Me http://tangent.org/ <-- Software _______________________________________________________ You can't grep a dead tree.
