public interface IDGenerator

Generator of record IDs for the journals.

Notice that while the bindings and messages journals are independent from one another they use the same IDGenerator instance.

The next recordID should be persisted in the journals during a normal shutdown. The lack of such a record indicates a server crash. During server restart, if the journals lack a next-recordID record, we use the last recorded ID plus MAX_INT.
