Subject [jira] [Created] (HIVE-5756) Implement vectorization support for IF conditional expression
Date Wed, 06 Nov 2013 17:53:18 GMT
Eric Hanson created HIVE-5756:
---------------------------------

             Summary: Implement vectorization support for IF conditional expression
                 Key: HIVE-5756
                 URL: https://issues.apache.org/jira/browse/HIVE-5756
             Project: Hive
          Issue Type: Sub-task
            Reporter: Eric Hanson


Implement full, end-to-end support for IF in vectorized mode, including new VectorExpression
class(es), VectorizationContext translation to a VectorExpression, and unit tests for these,
as well as end-to-end ad hoc testing. An end-to-end .q test is recommended but optional.

This is high priority because IF is the most popular conditional expression.
