I'll let others say how it picks which among available competing consumers gets the next message, but there are two customizations that I'm aware of: the exclusive consumer flag (changing load balancing to failover, effectively) and message groups, which provide a form of consumer affinity, so that messages in the same message group are delivered to the same consumer, until/unless that consumer goes away, in which case a new consumer claims the group as a whole.
