1. Data recovery. As long as there is a backup of the database at a certain time and all the binlog after this time, the data of the database can be restored.

In our daily work, our DBA students can often help us recover the data from the database to any second.

2. Master-slave replication. In order to improve the efficiency of MySQL, we often do read-write separation, that is, one master and multiple slaves.

One master library (write library) and multiple slave libraries (read library).

At this point, the slave library can monitor the binlog log of the master library and write all changes to the library synchronously.
