The riak package

[Tags:benchmark, library, test]

A Haskell client library for the Riak decentralized data store, designed for efficiency, ease of use, and flexibility. Uses the Riak protocol buffers API for speed.

This library is organized to allow a tradeoff between power and ease of use. If you would like a different degree of automation with storage and conflict resolution, you may want to use one of the following modules (ranked from easiest to most tricky to use):

JSON for storage, automatic conflict resolution. This is the easiest module to work with.
JSON for storage, manual conflict resolution.
More complex (but still automatic) storage, automatic conflict resolution.
More complex (but still automatic) storage, manual conflict resolution.
manual storage, manual conflict resolution. This is the most demanding module to work with, as you must encode and decode data yourself, and handle all conflict resolution yourself.
