Riak Core--an open-source Erlang library created by Basho Technologies that powers Riak KV and Riak Search--allows developers to build distributed, scalable, failure-tolerant applications based on a generalized version of Amazon's Dynamo architecture. In this talk, Rusty will explain why Riak Core was built, discuss what problems it solves and how it works, and walk through the steps to using Riak Core in an Erlang application.
