    Description

      WeTune is a rule generator that can automatically discover new query rewrite rules for SQL query optimization.

       

      The paper was published in 2022, and some optimization rules have recently been implemented in Calcite.

      e.g. CALCITE-6214 is rule No.2 in Table.7 of the paper.

       

      But there are still many rules that have not been implemented,
      which are worth discussing.

      Here are all the discovered rewrite rules.
