“MySQL Replication is a feature of the MySQL server that allows
you to replicate data from one MySQL database server (called the
master) to one or more MySQL database servers (slaves). MySQL
Replication has been supported in MySQL for a very long time and is
an extremely flexible and powerful technology. Depending on the
configuration, you can replicate all databases, selected databases,
or even selected tables within a database.“Replication is asynchronous, that is, the process of
replication is not immediate and there is no guarantee that slaves
have the same contents as the master (this is in contrast to MySQL
Cluster).”
