Mck SembWever commented on CASSANDRA-1125: ------------------------------------------ Created CASSANDRA-2878 for the better solution using a IndexClause > Filter out ColumnFamily rows that aren't part of the query (using a KeyRange) > ----------------------------------------------------------------------------- > > Key: CASSANDRA-1125 > 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: 1.0 > > Attachments: 1125-formatted.txt, 1125-v3.txt, CASSANDRA-1125.patch, > CASSANDRA-1125.patch > > > 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. -- This message is automatically generated by JIRA.
