Reserved Topics
Solace PubSub+ uses a number of reserved topics to implement some specific messaging features. Each of these topic subscriptions begin with the # character, which is then followed by a specific, reserved sequence of characters. Some special topics only use a reserved string for the first hierarchical level of the topic subscription, others may reserve more than one level.
Any topic starting with # is reserved for special topics. Topics defined by applications must not start with #. As an exception to this rule—with request/reply across multi-node routing networks, where a subscription propagation delay may occur—topics of the form #P2P/v:routerName/ can be used.
