Memcache cluster
 

Has anyone ever done this? Benefits over Redis cluster? :confused:

memcache doesn't cluster it's just a farm (it has not single master node, all the servers are ignorant of one another) so you really are not going to be making a true cluster with it.

As for redis not sure.. can anyone comment?

Redis Cluster tries harder to retain writes that are performed by clients connected to the majority of masters, compared to writes performed in the minority side.

Memcached server is entirely blind to which objects stored over it. This unpretentious architecture enables Memcached to be effective and fast but comes with poor dependability, which is undesirable for most web applications these days.

Memcache is volatile memory server.Memcache is used for caching while Radis used as database as well as caching system.

Radis is faster than Memcache. You can specify the size to Memcache and it will use too much space compare to Radis. Radis will provide the space back if it is not used.
