Description

When a notification results in creation of an entity, Atlas saves the classifications given in the notification (as entity didn’t exist in Atlas, this is not considered as an update to classifications). Atlas should propagate the classifications added here only when "isPropagate" flag is set to 'true'. In other cases, the classifications should not be propagated.

Please note that notifications are meant to ingest metadata from source systems, and not an interface to add/update business metadata - such as classifications. Add/update/remove of classifications via notifications is not supported - except for the new entities created while processing notifications. If a notification results in update to an existing entity, Atlas ignores classifications in the notification. Changes to classifications must be done via appropriate REST API calls.
