@ -25,6 +25,10 @@ SeaweedMQ is designed for use cases that need to:
* Pass messages by reference instead of copying.
* Clients can optionally upload the messages first and just submit the references.
* Drastically reduce the broker load.
* Stateless brokers
* All brokers are equal. One broker is dynamically picked as the leader.
* Add brokers at any time.
* Allow rolling restart brokers or remove brokers at a pace.
