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 …

Today 23 May 2020, it is 25 years since the first release of MySQL. So, I would like to take the opportunity to wish MySQL – and Sakila – a happy birthday.

My own MySQL journey started in 2006 when I at a job interview was told that if I got the job, I would need to learn MySQL before starting. Since the job involved PHP coding, I got the book Web Database Applications with PHP and MySQL as well as Managing and Using MySQL. Around a week later, I started in my first job involving MySQL at Noggin Pty Ltd.

The two first MySQL books, I studied.

This was in the days of MySQL 5.0 when stored functions, procedures, and triggers were new, and statement based replication was the only binary log format around. The job evolved into including …

MySQL does not limit the number of slaves that you can connect to the master server in a replication topology. However, as the number of slaves increases, they will have a toll on the master resources because the binary logs will need to be served to different slaves working at different speeds. If the data churn on the master is high, the serving of binary logs alone could saturate the network interface of the master.

A classic solution for this problem is to deploy a binlog server – an intermediate proxy server that sits between the master and its slaves. The binlog server is set up as a slave to the master, and in turn, acts as a master to the original set of slaves. It receives binary log events from the master, does not apply these events, but serves them to all the other slaves. This way, the load on the master is tremendously reduced, and at the same time, the binlog server serves …

Database backups are a fundamental requirement in almost every implementation, no matter the size of the company or the nature of the application. Taking a backup should be a simple task that can be automated to ensure it’s done consistently and on schedule. Percona has an enterprise-grade backup tool, Percona XtraBackup, that can be used to accomplish these tasks. Percona also has a Percona Kubernetes Operator for Percona XtraDB Cluster (PXC Operator), which has Percona XtraBackup built into it. Percona XtraBackup has the ability for both automated and on-demand backups. Today we will explore taking backups and restoring these backups using the PXC Operator deployed …

MinervaDB Webinar – Building MySQL Database Infrastructure for Performance and Reliability

Recently I did a webinar on ” Building MySQL Database Infrastructure for Performance and Reliability ” , It was big success and thought will share the slides of webinar in this blog. I get lot of emails daily from Database Architects, DBAs, Database Engineers, Technical Managers and Developers worldwide on best practices and checklist to build MySQL for performance, scalability, high availability and database SRE, The objective of this webinar is to share with them a cockpit view of MySQL infrastructure operations from MinervaDB perspective. Database Systems are growing faster than ever, The modern datanomy businesses like Facebook, Uber, Airbnb, LinkedIn etc. are powered by Database Systems, This makes Database Infrastructure operationally complex and we can’t technically scale such systems with eyeballs. Building MySQL …

Today is a good day for me. Today I tweeted that MySQL after 25 years is still GPL and same for all important components: the server, the shell, the router, the clone plugin, workbench !

To be honest, Oracle has been a very good steward for MySQL so far, PZ and Kaj admitted it too. This exactly what I was thinking when I joined the MySQL family and I’m still convinced about it after 4 years… and never as much as now !

If you know me, you should know that for more than 20 years I always praised and defended Open Source! All kind, not only MySQL! I started of course with Linux and then a huge amount of projects where I dedicated time, docs, code, bug reports, chats… As you know I also worked for Stone-IT, X-tend, …

Why Should My Company Invest in Training?

In my interview with Shane Atherholt, Head of ISVs at MySQL, I asked him several questions: What is an ISV?  What is a SaaS application? How are ISVs using MySQL?

We also went over the recent data breaches and new government regulations. I asked how MySQL helps ISVs secure their data and comply with the new regulations. I also asked Shane what were ISV CEOs and CIOs top priorities and why they should consider a relationship with Oracle. In conclusion, we talked about what we should look forward to in the future with MySQL. Watch the interview below.

On May 27th, 2020, Shane Atherholt will hold a webinar focused on SaaS solutions for ISVs where he will go into more in depth detail about the MySQL offering for ISVs and SaaS. He will also cover the many MySQL Enterprise edition features that are designed to help ISVs with their SaaS applications so they can be more …
