In this post, we’ll discuss how an integrated ProxySQL and Percona XtraDB Cluster (Galera) helps manage node states and failovers.

ProxySQL is designed to not perform any specialized operation in relation to the servers with which it communicates. Instead, it uses an event scheduler to extend functionalities and cover any special needs.

Given that specialized products like Percona XtraDB Cluster are not managed by ProxySQL, they require the design and implementation of good/efficient extensions.

In this article, I will illustrate how Percona XtraDB Cluster/Galera can be integrated with ProxySQL to get the best from both.

Brief digression

Before discussing their integration, we need to review a couple of very important concepts in ProxySQL. ProxySQL has a very important logical component: Hostgroup(s) (HG).

A hostgroup is a relation …

I recently had the pleasure of attending the first OpenStack Days East conference in NYC. This was the first OpenStack Days event that we’ve had on the East Coast of the US, but I hope that it’s the first of many!…

Hi all, here is a new post following the blog series on the last MySQLvGroup Replication labs release which already presented: 1) the new features; 2) most asked questions; 3) summary of behaviour and configuration changes; and 4) the performance improvements.…

This blog is a 2nd part of a multi-part series on areas of  failover for MySQL.  The first installment looked at design considerations, giving us a “thinking” perspective on what we might want to adopt.  Later I will take a look at more of a business and operational way of thinking through these details.  In… Read More »

Group Replication introduces a new way to do replication in MySQL. With great features such as multi-master replication it brings a range of exciting deployment scenarios where some difficult problems become much easier to solve. Group Replication also brings a new set of options that may need to be configured to extract the highest performance from the underlying computing resources.…

This will be a multi-part series covering various areas of failover for MySQL.  This first installment will primarily look at some design considerations, which you can then apply to your own environment in your own way.  The concepts presented here are merely suggestions and not out-right “how-to”.   Every company has specific technologies or skill-sets in… Read More »

Hi everyone, its been a while since the last release of Group Replication. During this period we have been working hard to improve the plugin and give you a better user experience. Focused on solving several existing bugs, address performance issues and improving user
experience we renamed some variables, introduced new ones and changed some of the plugin policies.…

With the new Group Replication Beta release—0.8 for MySQL 5.7.14—available for download on labs.mysql.com, I expect more and more people to begin engaging in various forms of proof-of-concept attempts. So I wanted to create a “quick start guide” (to replace this outdated getting started post) focused on an example/test Linux environment, that covers how to get started, what a full working example test setup can look like, and also include some best practice and operations advice along the way.…

Hi everyone! It has been some time since the last MySQL Group Replication labs release was out. But the team has not been sitting on its hands. As such, it is time for a new labs release with new features, bug fixes and improvements across the board.…

Please join Percona, Technical Account Manager, Michael Patrick on Thursday, June 23, 2016 at 10 AM PDT (UTC-7) as he presents “Choosing a MySQL High Availability Solution Today.”

High availability (HA) is one of the solutions to improve performance, avoid data outages, and recover quickly from disasters. An HA environment helps guarantee that your database doesn’t have a single point of failure, accommodates rapid growth and exponentially increasing database size, and enables the applications that power your business.

Michael will discuss various topologies for achieving High Availability with MySQL.

Topics include:

• Percona XtraDB Cluster
• DRBD
• MHA
• MySQL Orchestrator

Each solution has advantages and …
