Riak is another new and interesting key-value store entrant. Some of the features it offers are:

Document-oriented
Scalable, decentralized key-value store
Standard get, put, and delete operations.
Distributed, fault-tolerant storage solution.
Configurable levels of consistency, availability, and partition tolerance
Support for Erlang, Ruby, PHP, Javascript, Java, Python, HTTP
open source and NoSQL
Pluggable backends
Eventing system
Monitoring
Inter-cluster replication
Links between records that can be traversed.
Map/Reduce. Functions are executed on the data node. One interesting difference is that a list keys are required to specify which values are operated on as apposed to running calculations on all values.
