Hi, PMC & commiters
I have come up with an issue about common subexpression elimination https://issues.apache.org/jira/browse/FLINK-23555 I hacked on the flink-table-planner module to improve common subexpression elimination by using localRef And the result tells that my hacked codes make a big difference. The issue has been proposed several days but got little attention. Now I don't know how to show you my code hence don't know if it's suitable. I need help and long for your attention. Yours sincerely
