In an effort to make Hadoop/MapReduce on Cassandra more accessible, we added a REST layer to Virgil that allows you to run map reduce jobs written in Ruby against column families in Cassandra by simply posting the ruby script to a URL. This greatly reduces the skill set required to write and deploy the jobs, and allows users to rapidly develop analytics for data store in Cassandra.
Smart: 10. Security: ?. Utility: 10.
