Subject [jira] [Created] (HIVE-12290) Native Vector ReduceSink
Date Thu, 29 Oct 2015 09:18:27 GMT
Matt McCline created HIVE-12290:

             Summary: Native Vector ReduceSink
                 Key: HIVE-12290
             Project: Hive
          Issue Type: Improvement
          Components: Hive
            Reporter: Matt McCline
            Assignee: Matt McCline
            Priority: Critical

Currently, VectorReduceSinkOperator is a pass-thru to ReduceSinkOperator, so we incur object
inspector costs.

Native vectorization will not use object inspectors and allocate memory up front that will
be reused for each batch.
