Exploring MySQL Binlog Server – Ripple

MySQL does not limit the number of slaves that you can connect to the master server in a replication topology. However, as the number of slaves increases, they will have a toll on the master resources because the binary logs will need to be served to different slaves working at different speeds. If the data churn on the master is high, the serving of binary logs alone could saturate the network interface of the master.

A classic solution for this problem is to deploy a binlog server – an intermediate proxy server that sits between the master and its slaves. The binlog server is set up as a slave to the master, and in turn, acts as a master to the original set of slaves. It receives binary log events from the master, does not apply these events, but serves them to all the other slaves. This way, the load on the master is tremendously reduced, and at the same time, the binlog server serves …

How to upgrade your master server with minimal downtime

Here’s a step-by-step guide on how to invert roles for master and slave so you can perform a master server upgrade, and then switch roles back to the original setup.

* While following this guide consider server-A as your original master and server-B as your original slave. We will assume server-B already produces binlogs and that both nodes have log-slave-updates=1 in my.cnf

Check this following link for more details on log-slave-updates:

1. Prepare the original Slave to invert roles.

Make sure the slave is …
