> After reconnecting, the consumer starts to read already read but unacked messages. Yes, this is the correct behavior. When a connection is established for the first time, messages 0, 2, 4, 6, and 8 will be acked. When reconnecting, the broker will re-send these unacked messages 1, 3, 5, 7, and 9 to the client. At this time, the messages may be repeated, so there is no way to guarantee the order of the messages, so you may encounter the situation you saw above. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
