Client State
When a connection is established between your Broker client and a Broker, the Broker creates and maintains a client state that includes the following information:
A client identifier that uniquely identifies your
Broker client to a particular
Broker.
A queue where events received for your
Broker client will be stored until they are retrieved.
A list of event subscriptions for your
Broker client.
The
client group with which your
Broker client is associated.
A single client state can be shared by multiple
Broker clients, as described in
Sharing Client State.
