[jira] Created: (PIG-1438) [Performance] MultiQueryOptimizer should
also merge DISTINCT jobs
[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
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).
