What are the major differences between Redis and Membase?
Membase is a massive key-value store with persistent and replication for failover. The data stored in membase is not subject to "modification" (besides increment). You get or set it.
Redis is more of a key-data store. Redis allows the manipulation of sets, lists, sorted-lists, hashes and some odd other data types. While redis has replication it is more of a master/slave type of replication.
