I agree, moving the `RexNode` translation to the individual `Expression` makes a lot of sense. I only skimmed the PR and did not have a detailed look but everything looks fine. Will check the PR more thoroughly tomorrow and probably merge it. > Move toRexNode and toAggCall logic into Expressions > --------------------------------------------------- > > Key: FLINK-3736 > URL: https://issues.apache.org/jira/browse/FLINK-3736 > Project: Flink > Issue Type: Improvement > Components: Table API > Reporter: Yijie Shen > Priority: Minor > > Since we have a one-to-one mapping from Flink {{Expression}} to Calcite > {{RexNode}}, and we will implement more and more expressions to make > flink-table a full-fledged module, I think it's worthwhile to let each > {{Expression}} take care of its own behaviour on conversion to {{RexNode}}. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
