Re: [Query] Can we use calcite for rewriting the query based on Materialized View
Yes, it is possible.
As long as you have your schema defined you can create a Planner (Volcano,
or Heuristic) with the appropriate rules for view based rewritting and
obtain a plan that is using the views. Then you can pass from a plan back
to sql using RelToSqlConverter.
You might find interesting the discussion in . You can also have a look
in the MaterializationTest which can serve as an entry point in order to
understand how the rewritting works.
