Propagation of tags as deferred actions

By default, Atlas asynchronously propagates tags along a lineage while processing other tasks. Depending on your scenario, you can disable the propagation of tags as deferred action. This might help you to save compute resources and time for other Atlas processes at the cost that the tag propagation finishes later.

To control tag propagation, you can set the value of the atlas.tasks.enabled property. By default, this is set to true. You can set this property in Cloudera Manager under Atlas Server Advanced Configuration Snippet (Safety Valve) for conf/atlas-application.properties.

While the background task is processing the tag propagation request, you can view the notification of propagation of tags in the Atlas UI on the Entities details page. The Task tab displays the progress of this request.
