Xiao Li resolved SPARK-25716. ----------------------------- Resolution: Fixed Assignee: SongYadong Fix Version/s: 3.0.0 > Project and Aggregate generate valid constraints with unnecessary operation > --------------------------------------------------------------------------- > > Key: SPARK-25716 > URL: https://issues.apache.org/jira/browse/SPARK-25716 > Project: Spark > Issue Type: Improvement > Components: SQL > Affects Versions: 3.0.0 > Reporter: SongYadong > Assignee: SongYadong > Priority: Minor > Fix For: 3.0.0 > > Original Estimate: 24h > Remaining Estimate: 24h > > Project logical operator generates valid constraints using two opposite > operations. It substracts child constraints from all constraints, than union > child constraints again. I think it may be not necessary. > Aggregate operator has the same problem with Project. > for example: > in LogicalPlan.getAliasedConstraints(), return: > {code:java} > allConstraints -- child.constraints{code} > in Project.validConstraints(): > {code:java} > child.constraints.union(getAliasedConstraints(projectList)){code} -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
