memcached best practices

[Jason Edgecombe]

Hi everyone,

I've been looking for some more documentation on the best practices for 
using memcached. I checked google and sarafibooks online. Are there any 
good documents on best practice?

My specific situation is this:
I'm trying to tweak the b2evolution weblog software 
(http://www.b2evolution.net) to use memcached. There are already several 
associative arrays that are used to cache DB queries during a single 
http request. I currently, load the cache arrays from memcached at the 
start of the request and save the variable at the end. I suspect that 
this doesn't make for good cache consistency. I would love any critique 
as this is my first real exposure to memcached. I am using the phpca php 
memcached client. In addition to wanting to add memcache support, I also 
want the software to function correctly without it.

Any advice is greatly appreciated.

Sincerely,
Jason Edgecombe
