MergeableMemcacheStore

class MergeableMemcacheStore[K, V] extends ConvertedStore[String, K, ChannelBuffer, V] with MergeableStore[K, V]

Mergeable MemcacheStore that uses CAS.

The store supports multiple concurrent writes to the same key, but you might see a performance hit if there are too many concurrent writes to a hot key. The solution is to group by a hot key, and use only a single (or few) writers to that key.
