Effortlessly Scaling out Galera Cluster with ProxySQL

A blog series about ProxySQL and Galera…

This post is the first of a series of blogposts on how to easily use ProxySQL to scale-out your application’s database workload on a Galera cluster. This series will explore the main concepts in configuring ProxySQL for Galera across three articles as follows:

– A first introductory post describing the minimal configuration needed for ProxySQL to monitor and manage a Galera Cluster.
– A second post describing how to setup a read/write split configuration for our Galera Cluster, using ProxySQL query rules.
– A third and final post with examples on specific cluster configuration options and more detailed explanations on why and how ProxySQL changes the nodes states based on configuration changes and monitored variables. Requirements

To illustrate how to configure ProxySQL for a Galera Cluster we will use a sample Galera Cluster

Evaluating Percona XtraDB Cluster 8.0 in I/O Bound Workload

Percona XtraDB Cluster 8.0 is in the final stretch before GA release and we have pre-release packages available for testing, and I wanted to see how Percona XtraDB Cluster 8.0 performs in CPU and IO-bound scenarios, like in my previous posts about MySQL Group Replication.

In this blog, I want to evaluate Percona XtraDB Cluster 8.0 scaling capabilities in I/O bound cases when we increase the number of nodes and increase user connections. The version I used is available here: …

Congratulations to the MariaDB Foundation for releasing a generally available (GA) stable version of MariaDB Server 10.2! We’ll definitely spend the next few weeks talking about MariaDB Server 10.2, but here’s a quick overview in the meantime. Keep in mind that when thinking about compatibility, this is meant to be the equivalent of MySQL 5.7 (GA: October 21, 2015, with Percona Server for MySQL 5.7 GA available February 23, 2016).

9 Tips for Going in Production with Galera Cluster for MySQL

August 25, 2014 By Severalnines

Are you going in production with Galera Cluster for MySQL? Here are 9 tips to consider before going live. These are applicable to all 3 Galera versions (Codership, Percona XtraDB Cluster and MariaDB Galera Cluster). 

 

1. Galera strengths and weaknesses

 

There are multiple types of replication and cluster technologies for MySQL, make sure you understand how Galera works so you set the right expectations. Applications that run on single instance MySQL might not work well on Galera, you might need to make some changes to the application or the workload might not be appropriate. We’d suggest you have a look at these resources:

Webinar: Migrating to MySQL, MariaDB Galera and/or Percona XtraDB Cluster

February 13, 2014 By Severalnines

 

Galera is slowly but surely establishing itself as a credible replacement for traditional MySQL master-slave architectures. 

The benefits are clear - a true multi-master InnoDB setup with built-in fail-over, potentially across data centers. 

But how do you migrate? Does the schema or application change? What are the limitations? Can migration be done online, without service interruption? What are the potential risks, and how to address those?
