public static interface Subscriber.GroupId
Subscribers with the same group id belong to the same subscriber group.
Conceptually you can think of a subscriber group as being a single logical
subscriber that happens to be made up of multiple processes.
Subscriber groups allow a pool of processes to divide the work of consuming
and processing records. These processes can either be running on the same
machine or, as is more likely, they can be distributed over many machines
to provide scalability and fault tolerance for processing.
