We are very excited about the next release of MySQL Group Replication 0.9.0 in MySQL 5.7.15 and the great work that has been done to improve its stability. Release after release, MySQL Group Replication becomes more stable and more user-friendly and has reached a maturity level that made us declare 0.9.0 a release candidate.…

In this blog post we will present a first look at the performance of Group Replication (GR), now that the RC is out. The goal is to provide some insight on the throughput, latency and scalability one can expect in a modern computing infrastructure, using GR in single- and multi-master configurations, but mostly focused on single-master.…

Hi all, it is time again to do another preview release of MySQL Group Replication, the plugin that brings multi-master update everywhere support to MySQL, like we described in the Hello World post.

We are very proud to present the eighth preview release of MySQL Group Replication plugin, based on MySQL Server 5.7.15.…

Vadim Tkachenko recently released  Docker images for Group Replication (thank you for that ).

As not everybody is already using Docker or just because having multiple choices is also nice (this is an OpenSource world isn’t it ?), I decided to share a Vagrant environment that you can use to evaluate Group Replication.

This environment provides also a module that can be used to deploy GR on any other environment managed by Puppet.

The repository is available on my github account: mysqlGR-vagrant

This is a quick demo on how to use it:

Tadam ! You have a MySQL Group of 3 members ready to use !

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.…

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.…

In this post, I will point you to Docker images for MySQL Group Replication testing.

There is a new release of MySQL Group Replication plugin for MySQL 5.7.14. It’s a “beta” plugin and it is probably the last (or at lease one of the final pre-release packages) before Group Replication goes GA (during Oracle OpenWorld 2016, in our best guess).

Since it is close to GA, it would be great to get a better understanding of this new technology. Unfortunately, MySQL Group Replication installation process isn’t very user-friendly.

Or, to put it another way, totally un-user-friendly! It consists of a mere “50 easy steps” – by which I think they mean “easy” to mess up.

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.…
