-"""
-Each Data Stream can be grouped in a logical set with a dedicated portal type which represents the set.
-
-For ebulk this portal type is "Data Set" but in theory it can be anything. Thus name of script is intentionally using 'Set'.
-
-This script works for the  default ingestion model used by ebulk:
-- Data Ingestion
-  - Data Ingestion Line
-     (aggregate) -> Data Stream
-     (aggregate) -> Date Set
-
-Note: for this to work we must working an index relation between Data Ingestion Line and Data Stream!
