A pipeline may report a successful run while loading no new records because a watermark has advanced incorrectly, source filters exclude current data, or the job reads from the wrong partition. A green status alone does not confirm that expected data arrived.
Compare source counts, watermark values, partition dates, filter parameters, and destination row changes. Review the run identifier and inspect a small sample of source records that should have been included.
Add an expected-volume or freshness check and alert when a completed run produces no data unexpectedly. Document how to reset a watermark safely and validate the affected period before replaying records.
