ID Generator used by Conductor Note on overriding the ID Generator: The default ID generator uses
UUID v4 as the ID format. By overriding this class it is possible to use different scheme for ID
generation. However, this is not normal and should only be done after very careful consideration.

<p>Please note, if you use Cassandra persistence, the schema uses UUID as the column type and the
IDs have to be valid UUIDs supported by Cassandra.
