Dear all, I am performing a Volcano optimisation pass first and I receive the root of the optimised plan from the standard Program in [1]. Afterwards, I want to perform a top-down pass to the optimised plan and change it a bit by placing certain operators at specific points.
Do you have any ideas on how to do this properly in Calcite? Thanks in advance. Best, Makis [1] — https://calcite.apache.org/apidocs/org/apache/calcite/tools/Programs.html <https://calcite.apache.org/apidocs/org/apache/calcite/tools/Programs.html>
