I think that when the client receives a SLAVE_NOT_AVAILABLE, the client must
resend the message, and it may still be sent to the abnormal broker.
Therefore I think that the message should not be returned when
SLAVE_NOT_AVAILABLE.

主题: Re: [apache/rocketmq] Why does case SLAVE_NOT_AVALIABLE roll back
when sending transaction messages (Issue #3617)
IMO, for the client, SLAVE_NOT_AVAILABLE is returned when sending a
transaction message. At this time, the message has been successfully written to
the master, and the client can resend it after ROLLBACK_MESSAGE.
For Broker, after receiving the commit message sent by the client, if
SLAVE_NOT_AVAILABLE occurs, the commit message has been written to the master
at this time, so it will automatically synchronize after the slave is restored,
otherwise it will not make any sense to resend the commit after the return
fails. .
