Dear all, For a project I want to retrieve the Calcite RelNodes during the execution of the queries (perhaps even before query optimisation if possible) and perform some analysis on those RelNodes. However, I am a bit stuck with the best way to approach this. Has something similar already been done which I can leverage?
Looking at the Hive Hooks, there exists a HookContext which contains the query state as a property. From there you can initialise a CalCitePlanner and call the genLogicalPlan function using an ASTNode. Would the original ASTNode of the query be stored somewhere? Is this also the preferred approach to get access to these calcite logical plans? With kind regards, Mark
