I think ultimately `port_id` should be part of the tracking. It seems this current version has many assumptions, e.g., a big object is only created by a FileScan operator, and the current version only tracks the source of bigObjects? We need to discuss which of these assumptions will be generalized in the future. -- This is an automated message from the Apache Git Service.
