The goal is to execute the mysqlrplsync utility to detect data consistency issues on an active replication system making sure that master and slaves are synchronized.

Executing this task manually on an active system is difficult and sometimes tedious since changes may be continuously happening on all servers (in an asynchronous way) and the same data needs to be compared between servers. Moreover, it can introduce an undesirable and uncontrolled impact on the system performance.

Fortunately, the mysqlrplsync utility allows us to perform this task in an easy and optimized way with a controlled impact on the running system (limiting the execution time of all operations).

Let's assume that a replication topology with one master (server1:3310) and two slaves (server2:3311, server3:3312) was previously setup and it is running without errors.
