I am using calcite right now to test some data federation scenarios. I have several collections of Java objects that I am querying right now. It works beautifully, but it seems like Calcite does a ton of work with each query and does not cache any of the work.
Is there a way for me to implement a plan cache within Calcite? Or is there already a mechanism for this? I tested implementing my own subclass of PreparedStatementFactory and caching the CalciteSignature for calls to prepareSql. This seems to work really well, but I am not sure if 1) this is safe to do and 2) is this the proper way to do it. Thanks for your help, Pau;
