Riak Core is a single OTP application which provides all the services necessary to write a modern, well-behaved distributed application. riak_core began as part of Riak. Since the code was generally useful in building all kinds of distributed applications we decided to refactor and separate the core bits into their own codebase to make it easier to use.
Distributed systems are complex and some of that complexity shows in the amount of features available in riak_core. This page will separate the features into broad categories and give an overview of each.
This section will be expanded on a lot in the coming weeks.
In the meantime, please feel free to check out Riak Core on the old Basho site.
