JMS specification dictates that the identification of S is done by a combination of the clientID and the durable subscriber name. So for durable topic subscription, the JMS provider needs to be able to identify S when it shuts down and later on in the future reconnects, so it can know what messages to send to it while it was not running. For non-durable topics, only messages delivered to the topic T when S is running are delivered. because the subscription is durable, S will receive every message sent to T whether the subscriber is running or not. If S were a non-durable consumer then it would only have received M1, M2, M3 and M6, M7 - not M4 and M5. This is the difference between durable and non-durable consuming. Now S will receive M4, M5 followed by M6 and M7 and all future messages. When S restarts at D2, the publisher sends M6 and M7.
Then S is stopped and the publisher continues to send M4, M5. Some publisher sends messages M1, M2, M3 to the topic and S will receive each of these messages. There is just one copy of a message that any consumer in the future can consume.ĭurable topics however are different as they must logically persist an instance of each suitable message for every durable consumer - since each durable consumer gets their own copy of the message.įor example imagine a durable subscriber S starts up subscribing to topic T at time D1. Durable queues do not need to concern themselves with which consumer is going to consume the messages at some point in the future.
