Disabling distributed notification processing

If you need to revert to serial processing after enabling the distributed framework, you must perform the operation safely to avoid data loss.

  1. Stop or pause incoming messages to Atlas.
  2. Monitor all ATLAS_METADATA_* and ATLAS_LINEAGE_* topics to ensure consumer lag reaches zero.
  3. Stop the Atlas service.
  4. Set atlas.notification.parallel.processing.enabled to false.
  5. Restart the Atlas service.
