Subject [jira] Created: (CASSANDRA-1125) Filter out ColumnFamily rows that aren't part of the query
Date Mon, 24 May 2010 23:26:23 GMT
Filter out ColumnFamily rows that aren't part of the query
----------------------------------------------------------

                 Key: CASSANDRA-1125
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-1125
             Project: Cassandra
          Issue Type: Improvement
          Components: Hadoop
            Reporter: Jeremy Hanna
            Priority: Minor


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.
