[jira] [Created] (PIG-3456) Some minor performance improvements

Rohini Palaniswamy created PIG-3456:
---------------------------------------

             Summary: Some minor performance improvements
                 Key: PIG-3456
                 URL: https://issues.apache.org/jira/browse/PIG-3456
             Project: Pig
          Issue Type: Improvement
            Reporter: Rohini Palaniswamy
            Assignee: Rohini Palaniswamy


Noticed few things while browsing code

1) DefaultTuple has a protected boolean isNull = false; which is never used. Removing this gives ~3-5% improvement for big jobs
2) Config checking with ThreadLocal conf is repeatedly done for each record. For eg: createDataBag in POCombinerPackage. But initialized only for first time in other places like POPackage, POJoinPackage, etc.
