`TableProvider` always return all columns in scanning, is it able to pushdown selections into `TableProvider` and return the schema after selections? I think it may be useful to reduce the memory usage in querying. Sorry I am not good at database querying, hope for your reply, thanks. -- This is an automated message from the Apache Git Service.
