[jira] [Created] (KYLIN-2636) optimize case when in group by

JIRA jira@apache.org
hongbin ma created KYLIN-2636:

             Summary: optimize case when in group by
                 Key: KYLIN-2636
                 URL: https://issues.apache.org/jira/browse/KYLIN-2636
             Project: Kylin
          Issue Type: Improvement
            Reporter: hongbin ma
            Assignee: hongbin ma

Similar to KYLIN-2635, for clauses like:

group by case when 1 = 1 then x 1 = 2 then y else z

kylin only need to pick up x as grouping by column.

Again, like KYLIN-2635, we'll fix it in KYLIN rather than calcite first
