Hi @lanlanbaby, it will not truncate the slave's commitLog between confirmOffset to maxOffset before the slave changing to master. First, the transfer of confirmOffset is delayed, if the commitLog between confirmOffset to maxOffset is truncated, messages may be lost. In addition, we only guarantee that messages will not be lost. Messages between confirmOffset to maxOffset are uncertain (no ack to clients), so it doesn't matter if these messages exist. -- This is an automated message from the Apache Git Service.
