Welcome to the first day of the Percona Live Open Source Database Conference 2017, and the first set of Percona Live keynotes!

It’s a beautiful day in Santa Clara, but we don’t know because we’re inside the Hyatt Regency Convention Center listening to various rock stars in the open source database community talk about open source technologies. Day one of the conference kicked off with four keynote talks, all of which discussed issues and technologies that are addressed by open source solutions:

In this blog post, I’ll discuss some of my thoughts about the future of MariaDB after attending the M17 Conference.

Let me start with full disclosure: I’m the CEO of Percona, and we compete with the MariaDB Corporation in providing Support for MariaDB and other services. I probably have some biases!

Last week I attended the MariaDB Developers UnConference and the M17 Conference, which provided great insights into MariaDB’s positioning as a project and as a business. Below are some of my thoughts as I attended various sessions at the …

This post is just following up my previous blog post which describes how to setup 3-nodes MariaDB Galera Cluster with MySQL-Sandbox on single server.

Today, I’ll try to explain how we can setup MariaDB MaxScale over the Galera Cluster. Before I move ahead, I would like to explain about MaxScale little bit.

MariaDB MaxScale is a database proxy that enables horizontal database scaling while maintaining a fast response to client applications. You can implement MaxScale on either MySQL Replication or Galera cluster. With MySQL Replication, you can either use Read/Write Splitting or Connection routing and same with Galera Cluster. You can get more information here about this product.

A basic MySQL or MariaDB replication arrangement uses a simple method to perform replication. Any changes to schema or data on the master are recorded in its binary log. The slave regularly asks the master for any new entries to its binary log, based on position numbers in that log. The slave will record any new entries the master sends it in a relay log and then execute them on its copy of the databases. This system works well with a straightforward master-slave configuration, when there is only one master and one or more slaves.

With recent releases of MySQL and MariaDB, a slave can have multiple sources for replication. This may seem absurd at first until you consider one of the inherent points of replication: load balancing. Slaves are typically used for Read load balancing—to spread traffic related to SELECT statements among several servers. With multi-source replication, Writes can also be load balanced. For a large organization with …

For the production environment, it’s recommended that we should use separate server for each Galera Cluster node but sometimes, for the testing purpose we have to setup it on one server with different ports. Here are the steps for how to do that with CentOS 6.8, MariaDB Galera Cluster 10.1.21 and MySQL Sandbox
