How to maintain cache update on different memcached servers?

[Adam Michaels]

You have to look at memcached and mysql as 2 seperate layers. Memcache is 
just one big network cache. Your memcache data would need to be in sync with 
the mysql master as that is your point of your data integrity. I would look 
at http://jan.kneschke.de/projects/mysql/udf/ for info on how to have the 
master keep your cache in sync for you.
