replication implmentation （Mysql）

Replication is based on the master serhttp://myrubylearning.wordpress.com/wp-admin/post-new.php?post_type=postver keeping track of all changes to its databases (updates, deletes, and so on) in its binary log.
Each slave that connects to the master requests a copy of the binary log.
Because each slave is independent, the replaying of the changes from the master’s binary log occurs independently on each slave that is connected to the master.
