> URL: https://issues.apache.org/jira/browse/CASSANDRA-1125
> Project: Cassandra
> Issue Type: New Feature
> Components: Hadoop
> Reporter: Jeremy Hanna
> Assignee: Mck SembWever
> Priority: Minor
> Fix For: 0.8.2

> 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.
