> When we create a materialized view, the query specified in the statement should be optimized by Calcite, as this might make a huge performance difference when we materialize the results.
> Further, Calcite optimization should be trigger too when we execute {{ALTER MATERIALIZED VIEW ... REBUILD}}, as the changes in the original tables might lead to a new optimized plan.
