Codership is proud to announce the first Generally Available (GA) release of Galera Cluster 4 for MySQL 8 and improve MySQL High Availability a great deal. The current release comes with MySQL 8.0.19 and includes the Galera Replication Library 4.5 with wsrep API version 26. You can download it now (and note that we have packages for various Linux distributions). 

Galera 4 and MySQL 8.0.19 have many new features, but here are some of the highlights:

• Streaming replication to support large transactions by splitting transaction replication then applying them in smaller fragments. You can use this feature to load data faster, as data is written to all nodes simultaneously (or not at all in case of a failure in any single node).
• Improved …

We recently covered Installing Galera Cluster 4 with MySQL 8 on Ubuntu 18.04 , the new Galera version for MySQL High Availability. We got a request to see if we would be able to install it on Amazon Linux 2, and the short answer is yes, we are able to deploy Galera Cluster on Amazon Linux 2.

We have even published Installing a Galera Cluster on AWS guide for Geo-distributed MySQL Multi-master clustering which covers how to install a 3-node Galera Cluster on CentOS 7 to achieve disaster recovery . It turns out, Amazon Linux 2 tends to be quite compatible with this article ( …

Since the beta of Galera Cluster 4 with MySQL 8 has been released, we’ve had people asking questions as to how to install it on Ubuntu 18.04. This blog post will cover just that.

Prerequisites

• All 3 nodes need to have Ubuntu 18.04 installed
• Firewall (if setup) needs to accept connections on 3306, 4444, 4567, 4568 (a default setup has the firewall disabled)
• AppArmor disabled (this is as simple as executing: systemctl stop apparmor and systemctl disable apparmor).

Installation and Configuration

We have good installation documentation as well as a quick how to get this installed in AWS (though this is CentOS centric).

First, you will need to ensure that the …

Percona Live Europe Amsterdam Day 1 was a bunch of fun, especially since I didn’t have to give a talk or anything since my tutorial was over on Day 0.

At lunch, I realised that there are a lot more fringe events happening around Percona Live… and if you’ve seen how people do “tech weeks”, maybe this is what the event ends up being – a show, plus plenty of focused satellite events. FOSDEM in the open source world totally gets this, and best of all, also lists fringe events (see example from 2019).

So, Thursday evening gets a few fringe events, a relatively short train ride away:

• ClickHouse Paris Meetup 2019
• …

We (Codership, the original and continued developers and experts of Galera Cluster) participated in Austin 2019, and so it would have seemed remiss if we did not also show up at the Percona Live Open Source Database Conference Europe 2019 (that was a mouthful!) happening in Amsterdam September 30 – October 2 2019. We have a booth in the expo hall at the Hilton Amsterdam Schipol Airport, so come drop by and say hello!

While we do not have any talks accepted in the main program, we do have a tutorial that involves using Galera Cluster and MariaDB Server on the first day at 9am by Colin Charles.  View the whole …

Do you think Quality Assurance (QA) is more than the simplistic view of bug hunting? Do you believe that QA is important to the entire software development lifecycle and want to focus on failure testing, process and performance control, as well as best practice adoption? Do you enjoy doing performance benchmarks and noticing regressions? Do you like to write about it, from internal reports to external blog posts?

Then why not take up a challenge at Codership, the makers of Galera Cluster, as we are looking for a Galera Cluster QA Engineer (job description at link).

We’re looking for someone who is able to work remotely, join a company meeting at least once per year, be comfortable with the use of Slack and email (asynchronous communication, for developing our virtually synchronous replication solution!), but most importantly enjoy testing the …
