For cold data synchronization, we can set the master to read-only and
restore it to writable after synchronization.
In addition, I also found that if there are two slaves, and one of them lags
too far behind, only the latest file will be synchronized.

主题: Re: [apache/rocketmq] Why only the last few files are synchronized
when the master-slave synchronization gap is large (Issue #3661)
It is not recommended to directly change the slave, a large number of cold
reads is likely to cause the mast broker to be unavailable
