[GitHub] [rocketmq] xhsky opened a new issue #2946: Can the multi-master mode achieve high data availability?
xhsky opened a new issue #2946:
URL: https://github.com/apache/rocketmq/issues/2946
This document(https://github.com/apache/rocketmq/blob/master/docs/en/operation.md#12-multi-master-mode ) says that if a single machine goes down, the messages on the machine that went down will be unavailable before recovery. If a topic is created on multiple masters, does the same message exist on multiple masters? Then during a downtime, the unconsumed messages can be consumed on other masters

No, the message will only exist in this group of brokers。you can quickly repair the master broker, or manually switch the slave broker to the master
