Difference between queue and topic

java topic kafka queue

Queue	Topic
The point-to-point or queue model works by the sender to receiver setup	Publish/subscriber or topic model works by bulletin setup
Acknowledgement of the identity of the receiver and oftentimes the sender	Anonymity in the identities of both the subscriber and publisher
Only allowed one recipient	Multiple recipients
The sender and receiver do not have to be both active at the same time	Timing is very vital
The sender will receive a notification when the message gets to the receiver	Not notify you with such, and there is even a risk that you will have no subscribers
