> I have a question, if we detect the sort information when initializing the physical plan, would it cause a performance regression since we need read meta of all the parquet files? Depends where you place the parquet metadata. We'll likely don't wanna pre-fetch metadata when constructing the physical plan. However you could store the metadata in some catalog or cache, in which case it could be available during planning. -- This is an automated message from the Apache Git Service.
