      Description

      Currently, when running a MapReduce job against data in a Cassandra data store, it reads through all the data for a particular ColumnFamily. This could be optimized to only read through those rows that have to do with the query.

      It's a small change but wanted to put it in Jira so that it didn't fall through the cracks.
