[jira] [Commented] (CALCITE-4192) When the relNode has passed the
AggregateProjectMergeRule rule, it will be wrong to calculate the column
blood relationship through RelMdColumnOrigins tool
[ https://issues.apache.org/jira/browse/CALCITE-4192?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17183857#comment-17183857 ]
lifangzheng commented on CALCITE-4192:
--------------------------------------
calcite will produce a project under agg to make sure that group set has a normalized index like this:

but AggregateProjectMergeRule broke the agreement as the issue described。
