hongbin ma created KYLIN-2635: --------------------------------- Summary: optimize determined case when filters Key: KYLIN-2635 URL: https://issues.apache.org/jira/browse/KYLIN-2635 Project: Kylin Issue Type: Bug Reporter: hongbin ma Assignee: hongbin ma
currently calcite will not handle with determined filter like: 1. where 1 = 1 => where true 2. where ( 1= 1 or x = 2) => where true 3. where case when 'a' = 'a' then x > 1 else x < 1 => where x > 1 the first two cases have been handled in KYLIN-2539, however the third case is not handled yet. This JIRA is to track the third case. In theory, this JIRA together with KYLIN-2539, KYLIN-2597 should be solved in calcite rather than KYLIN. However it's urgent demand so we'll fix in KYLIN first. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
