[jira] [Created] (HIVE-21510) Vectorization: add support for and/or for (constant,column) cases

Zoltan Haindrich created HIVE-21510:
---------------------------------------

             Summary: Vectorization: add support for and/or for (constant,column) cases
                 Key: HIVE-21510
                 URL: https://issues.apache.org/jira/browse/HIVE-21510
             Project: Hive
          Issue Type: Improvement
            Reporter: Zoltan Haindrich


After HIVE-21001 some selectExpressions will start using VectorUDFAdaptor for "null and x" expressions. Because right now there are 2-3 places from which rewrite will be done to the form of "null and/or x" form; it would be better to support it.

{code}
[...]
selectExpressions: VectorUDFAdaptor((null and dt1 is null))
[...]
usesVectorUDFAdaptor: true
[...]
{code}
