> Atlas server generates audit logs on changes to entities - like add/remove
> classifications, entity attribute updates, etc. Add/remove of classifications
> to an entity can result in multiple entities to be updated due to
> tag-propagation. In such cases, the time taken to create audit logs can be
> reduced by writing audits for all updated entities in one call to the audit
> store, instead of current implementation that writes audit logs for one
> entity at a time.
