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: {code} group by case when 1 = 1 then x 1 = 2 then y else z {code} 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 -- This message was sent by Atlassian JIRA (v6.3.15#6346)
