Ashutosh Chauhan commented on PIG-1438: --------------------------------------- +1 please commit. > [Performance] MultiQueryOptimizer should also merge DISTINCT jobs > ----------------------------------------------------------------- > > Key: PIG-1438 > URL: https://issues.apache.org/jira/browse/PIG-1438 > Project: Pig > Issue Type: Improvement > Components: impl > Affects Versions: 0.7.0 > Reporter: Richard Ding > Assignee: Richard Ding > Fix For: 0.8.0 > > Attachments: PIG-1438.patch, PIG-1438_1.patch > > > Current implementation doesn't merge jobs derived from DISTINCT statements. > The reason is that DISTINCT jobs are implemented using a special combiner > (DistinctCombiner). But we should be able to merge jobs that have the same > type of combiner (e.g. merge multiple DISTINCT jobs into one). -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
