The Dicer Slicelet supports such a pattern, you can poll the assignment directly on the Slicelet:

(btw the notification mechanism itself does not deliver the assignment to the application, only notifies the application that the assignment has changed: https://github.com/databricks/dicer/blob/master/dicer/extern...)
