What is the difference between topic and queue in jms

If not, there is a possibility of reallocating the messages. Moreover, there are no acknowledgements. Thus, it can lead to a publisher not having any subscribers.

The queue is the message-oriented middleware that holds the message until the receiver is ready. In contrast, the topic is the message-oriented middleware that is responsible for holding and delivering messages to subscribers.

Thus, this is the main difference between queue and topic. In point to point messaging, the sender stores the messages on the queue and the receiver reads the messages from the queue. On the other hand, in publisher, subscriber messaging, the sender stores the messages on the topic and topic delivers the messages to the subscribers.

Also, another difference between queue and topic is that queue works with a receiver while the topic works with multiple subscribers. It mainly supports two messaging models or domains which are point to point and publisher-subscriber. Point to point uses queue while publisher-subscriber uses topic. The main difference between queue and topic is that queue is the message-oriented middleware used in point to point message domain while the topic is the message-oriented middleware used in publisher-subscriber message domain.

Queue model is only allowed one recipient; topic, on the other hand, can have multiple recipients. In queue model, the sender and receiver do not have to be both active at the same time. In the topic model, timing is very vital. In the queue model, the sender will receive a notification when the message gets to the receiver. The topic model, on the other hand, will not notify you with such, and there is even a risk that you will have no subscribers.
