URL: https://github.com/apache/rocketmq/issues/4039
The RocketMQ version I am using is 4.5.0, and I am asking about progress in
a consumer cluster mode:
1. When the consumer synchronizes the offset to the Broker, it randomly
selects a Broker (Master or Slave);
code:
FindBrokerResult findBrokerResult =
this.mQClientFactory.findBrokerAddressInAdmin(mq.getBrokerName());
(MQClientInstance#findBrokerAddressInAdmin);
3. When the consumer starts, it will perform dynamic heavy load to the
Broker side to pull and cancel the offset of the consumption point, which is
also a randomly selected Broker. So the question is: how to ensure that the
pulled offset is the latest consumer synchronized to the Broker? If the pulled
Broker offset is 0, doesn't it have to be re-consumed every time?
