Riak KV

Riak KV is a distributed NoSQL key-value database originally developed by Basho Technologies, designed for high availability, fault tolerance, and horizontal scalability across commodity hardware. Riak exposes two client-facing APIs: a RESTful HTTP API for basic GET, PUT, POST, and DELETE operations, and a higher-performance Protocol Buffers (PBC) API spoken over TCP. Both APIs support buckets, objects, secondary indexes, search, MapReduce, and CRDT data types.

Riak KV publishes 6 APIs on the APIs.io network, including Mapred API, Ping API, Riak KV HTTP API API, and 3 more. Tagged areas include Database, NoSQL, Key-Value Store, Distributed Systems, and Open Source.

Riak KV’s developer surface includes authentication, documentation, and 11 more developer resources.
