zhangyixin1222 opened a new issue #1837: an idea about the performance improvement URL: https://github.com/apache/rocketmq/issues/1837 Combine with the work practice,in my own opinion,the mq need append a function to invoke some slave mq broker to remember store the specified time span(or may be the offset) messages,which can improve the performance when some receiver need to use the message in special time or after some lag problem of the receiver.The nameserver may be use to schedule the concrete details which is config by the user flexibly or changable or when the laged-message receiver append to the mq.In the k8s situation ,also can combine the pods expand peculiarity when use metric tool to add new broker to pass the lagged message to the later receiver.Or can flexible change the connect after the receiver catch with latest message and shut down the redundant broker.If some problems in the design,welcome to communicate me in private.
