G
gschofield

This document summarizes a presentation about Riak and Ruby. It discusses that Riak is an open source distributed key-value store influenced by Dynamo and the CAP theorem. It also describes using Riak with Ruby clients like riak-client and ripple to store and retrieve data, perform map-reduce queries, and model associations between objects.
