Subject [jira] [Created] (HIVE-18573) Use proper Calcite operator instead of UDFs
Date Mon, 29 Jan 2018 21:45:00 GMT
slim bouguerra created HIVE-18573:

             Summary: Use proper Calcite operator instead of UDFs
                 Key: HIVE-18573
             Project: Hive
          Issue Type: Bug
          Components: Hive
            Reporter: slim bouguerra

Currently, Hive is mostly using user-defined black box sql operators during Query planning.
It will be more beneficial to use proper calcite operators.

Also, Use a single name for Extract operator instead of a different name for every Unit,  

Same for Floor function. This will allow unifying the treatment per operator.
