Hope you have been following our recent webinars on MySQL, Galera Cluster, AWS monitoring and more.

We are coming up with a webinar series in association with Eric Vanier, a leading MySQL expert consultant. The series will provide a step-by-step process to optimize MySQL database performance.

This webinar series is for everyone who is looking for ways to monitor their MySQL databases, simplify the process to manually analyze queries and achieve faster issue resolution time.

Eric Vanier will focus on key problem areas that are faced by DBAs and Shree will provide a solution-driven demonstration to overcome issues while monitoring the database performance. To make it simple, the series will comprise of three parts:

Part – 1: MySQL Performance Tuning

Troubleshooting a MySQL …

MySQL is arguably the most popular and common RDBMS. The last major release was MySQL 5.7 back in 2013.

As of today, several development milestones were declared for MySQL v8.0, but there is no official release available yet.

Even though there is no official software release to download and use yet, the list of features for MySQL 8.0 was officially announced, which makes it a great point in time to talk about it and share these great enhancements with you.

So without further ado, let’s dive into listing the new comers to MySQL 8.0:

• Roles – Very exciting feature that allows to create roles in MySQL server and assign specific privileges to them. These roles can be assigned to users. So from now you don’t have to remember which permissions a programmer from team X needs, and should a QA from team Y needs privilege Z. Also, it’s very easy to set …

If you want to keep up with the newest MySQL developer milestones I have news for you: there is no upgrade available for milestone versions. The way to go is to remove old version and install new one, according to their website:

Upgrades between milestone releases (or from a milestone release to a GA release) are not supported. For example, upgrading from 8.0.0 to 8.0.1 is not supported, as neither are GA status releases.

So if you, like me, had the 8.0.0 version and want to test the 8.0.1 (alhtough 8.0.3 milestone is already in development) …

This tutorial explains how to setup and configure MySQL multi-master replication on Oracle Linux. Please note that even though the configuration is made under Oracle Linux, yet the steps and configuration are mainly the same to CentOS and Red Hat Linux.

In this blog, we will provide answers to the Q & A for the MySQL In the Cloud: Migration, Best Practices, High Availability, Scaling webinar.

First, we want to thank everybody for attending the June 7, 2017 webinar. The recording and slides for the webinar are available here. Below is the list of your questions that we were unable to answer during the webinar:

How does Percona XtraDB cluster work with AWS for MySQL clustering?

In the last couple of blogs, we covered how to run a Galera Cluster on Docker, whether on standalone Docker or on multi-host Docker Swarm with overlay network. In this blog post, we’ll look into running Galera Cluster on Kubernetes, an orchestration tool to run containers at scale. Some parts are different, such as how the application should connect to the cluster, how Kubernetes handles failover and how the load balancing works in Kubernetes.

Kubernetes vs Docker Swarm

Our ultimate target is to ensure Galera Cluster runs reliably in a container environment. We previously covered Docker Swarm, and it turned out that running Galera Cluster on it has a number of blockers, which prevent it from being production ready. Our journey now …

In this post, we’ll use a blog poll to find out what operating system you use to run your production database servers.

As databases grow to meet more challenges and expanding application demands, they must try and get the maximum amount of performance out of available resources. How they work with an operating system can affect many variables, and help or hinder performance. The operating system you use for your database can impact consumable choices (such as hardware and memory). The operation system you use can also impact your choice of database engine as well (or vice versa).

Please let us know what operating system you use to run your database. For this poll, we’re asking which operating system you use to actually run your production database server (not the base operating system).

If you’re running …

Recently I posted a blog on my time attending a DevOps event in Toronto.  In that blog I had intended to focus on the conference and highlight some of the topics that stood out for me.  In this blog though, I wanted to share what others were doing with containers like Docker, and particularly and… Read More »
