Hi. I have implemented an extension of org.apache.calcite.jdbc.Driver, and I have the model handler extend org.apache.calcite.avatica.HandlerImpl
For performance optimizations, I would like to test VolcanoPlanner vs. HepPlanner as the documentation says that the latter is faster. How is this to be configured? I could not find a hook point to return the planner to be used. Thank you. Meron
