Debian 10 released with MariaDB 10.3

The Debian project announced their 15th release, code name Buster, on July 6th 2019. Debian 10 ships with MariaDB 10.3 and Galera. There is no separate MariaDB Connector C package, but instead MariaDB 10.3 includes MariaDB Connector C 3.0. Like most other popular Linux distributions, Debian prefers MariaDB over the Oracle owned alternative and this […]

Running Galera Cluster effectively on Amazon Web Services (AWS) and comparing it to RDS and Aurora (EMEA and USA webinar)

Do you want to run Galera Cluster in the cloud? Why not learn to setup a 3-node Galera Cluster using Amazon Web Services (AWS) Elastic Compute Cloud (EC2), and run it yourself (3-node because this is the minimum preferred size; you can have a 5, 7, or 9 node cluster too — not in the demo though!). In this webinar, we will cover the steps to do this, with a demonstration of how easy it is for you to do. We will also cover how you may want to load balance traffic to your Galera Cluster using a proxy like ProxySQL.

In addition, we will cover why you may want to run a 3-node (or more) Galera Cluster (multi-master synchronous clusters) instead of (or in addition to) using Amazon Relational Database Service (RDS) MySQL, which has the ability to have asynchronous replication (Read Replicas), and High Availability provided by DRBD (Multi-AZ). We will also cover where Galera Cluster differs from Amazon Aurora RDS for MySQL.

Blog from the Top — The Changing Landscape of Open Source (MySQL) and Money

This is the first in a series of blog articles in which I will discuss the changing landscape of open source and money. Or, more specifically, open source databases and money. And even more specifically MySQL and its all variants (AWS Aurora, MariaDB, Percona Server, RDS/MySQL) and money. But before going too deep into what is changing, let’s review all the traditional business models in and around the MySQL marketplace.

In general, these are the following types of companies in the MySQL commercial ecosystem, sorted by total annual revenue and addressable market size:

  • Developers who do not aim to monetize the open source code, just provide value to others and hope to get development and other contributions in return. This is the purest form of open source. For example, all …

MySQL Support Engineer's Chronicles, Issue #10

As promised, I am trying to write one blog post in this series per week. So, even though writing about InnoDB row formats took a lot of time and efforts this weekend, I still plan to summarize my findings, questions, discussions, bugs and links I've collected over this week.

I've shared two links this week on Facebook that got a lot of comments (unlike links to my typical blog posts). The first one was to Marko Mäkelä's blog post at MariaDB.com, "

How to Perform Compatible Schema Changes in Percona XtraDB Cluster (Advanced Alternative)?

If you are using Galera replication, you know that schema changes may be a serious problem. With its current implementation, there is no way even a simple ALTER will be unobtrusive for live production traffic. It is a fact that with the default TOI alter method, Percona XtraDB Cluster (PXC) cluster suspends writes in order to execute the ALTER in the same order on all nodes.

For factual data structure changes, we have to adapt to the limitations, and either plan for a maintenance window, or use pt-online-schema-change, where interruptions should be very short. I suggest you be extra careful here, as normally you …
