Subject [jira] Created: (HIVE-1283) map join does not stream the big tables
Date Fri, 26 Mar 2010 01:10:27 GMT
map join does not stream the big tables

                 Key: HIVE-1283
                 URL: https://issues.apache.org/jira/browse/HIVE-1283
             Project: Hadoop Hive
          Issue Type: Improvement
          Components: Query Processor
            Reporter: Namit Jain

Currently, all the keys from the big table are read before the join is performed.

It might be very slow if there is a hue skew, it might be a good optimization to stream the
larger table
