Riak is an open source, distributed database.

Riak is an open source, distributed database. Riak is architected for:

Availability: Riak replicates and retrieves data intelligently so it is available for read and write operations, even in failure conditions; Fault-Tolerance: You can lose access to many nodes due to network partition or hardware failure without losing data; Operational Simplicity: Add new machines to your Riak cluster easily without incurring a larger operational burden – the same ops tasks apply to small clusters as large clusters; Scalability: Riak automatically distributes data around the cluster and yields a near-linear performance increase as you add capacity.
