I am a Calcite newbie. I try to bind a simple data store directly with Calcite, i.e. without going through all the adapter layer.
By browsing through portions of the code, I think the test util SqlToRelTestBase seems to be the best example. Is there any other stand alone example? Also is there a document to talk about the relationship between RelNode, Interpreter, and RexNode? In theory I could "interpret" the RelNode directly (with or without query optimization). Of course I want to leverage existing functionalities as much as possible. My goal eventually is to do distributed query. I am just learning the ropes. Any help is greatly appreciated. Thanks much!
