@peter-toth Thanks for the review. I agree with you that we don’t have a cost model to check whether materialization is the right call. Here we do not do any view materialization by default, only when user enabled the switch, we will do it. In production query we have many views that should be materialized to get better performance, so we want to add this ability. -- This is an automated message from the Apache Git Service.
