Current behavior: An ETL execution with multiple output datasets will be labeled with "Successful" status after any one of the outputs has finished indexing. If outputs vary significantly in size, larger outputs may not finish indexing (and therefore will not have new/updated data available) for some time after the ETL execution is marked as "Successful".
Expected/desired behavior: An ETL execution with multiple output datasets should be labeled with "Successful" status only after all of the outputs have finished indexing (i.e., "Successful" indicates all data processed by the ETL execution is fully available). Until that time, ETL status of "Running Indexing" would be more appropriate.
