MySQL replication Overview MySQL supports unidirectional and asynchronous replication. One server acts as the master server during the replication process, and one or more other servers act as slave servers. MySQL replication tracks all database changes (updates, deletions, and so on) in binary logs based on the master

1> the occurrence of semi-synchronous replication:By default, replication is asynchronous, that is, the client commits the transaction to the main library, and the main library writes the transaction to the storage engine and Binlog and returns it to the client immediately telling them that the transaction executed successfully. If the transaction is not yet replicated to the slave library at this point, if
