Review Comment: ```suggestion Prepare a list of plan tasks that can be used later for table scan planning. Each plan task in the response of this API can be used as the `plan-task` in the `PlanTable` API request to plan table scan tasks against a subset of the table files. This can be used to parallelize and distribute table scan planning. ``` -- This is an automated message from the Apache Git Service.
