Research direction
Start by tracing the ODPS-to-ADS migration job configuration and its data-transfer entry points. Check whether a row-count limit is already supported or documented, then define and verify the expected behavior for a configured maximum. Done means a job can migrate only the requested number of rows without affecting other migration settings.
