   > emm, what do you mean by "only these two places are ok, the message is send successfully "? the broker sends to the producer or sends to the consumer?
   > I know the ack message will be sent to producer when these two places are ready. But when the consumer pulls the message from the broker, I do not find the code that gurantee thoses two places are ready.
   
   you are right，sorry。I reviewed the relevant code，It is possible that the message was consumed without flashing the disk and backing up to the standby node。But the message will still be flashed and synchronized to the standby node at the end
