Overview of this book

This book is aimed at system administrators/architects or DBAs who want to learn more about how to grow their current infrastructure to support larger traffic. Before beginning with this book, we expect you to be well-practiced with MySQL/MariaDB for common usage. You will be able to get a grasp quickly if you are comfortable with learning and building large infrastructures for MariaDB using Linux.

Chapter 4. MariaDB Replication

MariaDB replication is a mechanism that permits us to replicate data to another instance on another host. Replication is generally used for the following reasons:

  • Scale out reads: Replication permits scaling between several read databases to grow the read capacity
  • Providing high availability: With multiple slaves, you have no read Single Point Of Failure (SPOF)
  • Data analysis: Replication can be useful to have a replicated environment to allow querying without impacting the production environment
  • Disaster recovery: You can have a distant copy of a master if a major issue occurs on your primary site
  • Security: Replication can be used to add a read-only database on a DMZ for example

Replication works in an asynchronous mode, which means, if you have a low or degraded bandwidth, you will have a replication delta (slave late/with more delay) depending on your write load. The more write queries you have, the more information will need to be replicated and the...
