Best Practice

1. Only pending export jobs in PENDING, IN_QUEUE,EXPORTING state can be canceled.
2. When performing batch undo, Doris does not guarantee the atomic undo of all corresponding export jobs. That is, it is possible that only some of the export jobs were successfully undone. The user can view the job status through the SHOW EXPORT statement and try to execute the CANCEL EXPORT statement repeatedly.
3. When the job of the EXPORTING state is revoked, part of the data may have been exported to the storage system, and the user needs to process (delete) this section to export data.
