Hello, On a project, I needed to get different operator trees for a query, a functionality I implemented in VolcanoPlanner. I was successful in obtaining different operator trees when using calcite using sqlline(as specified in the tutorial).
However, I am trying to use VolcanoPlanner in Hive instead of HepPlanner, and the VolcanoPlanner object does not create the different operator trees and I get the initial query plan, unmodified. I suspect an incorrect instantiation of the VolcanoPlanner class. Can we transition from HepPlanner to VolcanoPlanner? What would be the steps needed to do this? I would appreciate pointers in this regard. Thank you, Kausik -- Kausik Subramanian CS PhD Graduate | University of Wisconsin-Madison
