Julian Hyde commented on CALCITE-2621: -------------------------------------- I'm not a fan of making things configurable unless there is a reasonable chance that someone will want to do something other than the default. In my opinion every configuration parameter is a design failure. Good products have fewer configuration parameters than bad ones, but more capabilities. > New rule: SemiJoinToCorrelateRule (SemiJoin => LogicalCorrelate) > ---------------------------------------------------------------- > > Key: CALCITE-2621 > URL: https://issues.apache.org/jira/browse/CALCITE-2621 > Project: Calcite > Issue Type: Improvement > Reporter: Ruben Quesada Lopez > Assignee: Julian Hyde > Priority: Major > Fix For: 1.18.0 > > > Similarly to JoinToCorrelateRule, in some contexts it might be interesting to > transform a SemiJoin into a LogicalCorrelate, for this purpose a > SemiJoinToCorrelateRule will be needed. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
