MariaDB 10.0.8 was recently released as RC ("Release Candidate"), and is available for download here:
https://downloads.mariadb.org/mariadb/10.0.8/
This is the first RC release of MariaDB 10.0. It is primarily a bug-fix and polishing release, and all features planned for MariaDB 10.0 GA are included in this release.
There were 6 notable changes in MariaDB 10.0.8:
The first blogpost in this series did a quick introduction to MaxScale, but now it is time start getting our hands dirty. We will get a more practical view on MaxScale and begin to put it to work. The following is based on a simple Proof of Concept that I did recently. The application is a mid-size web-based online shop where scalability is becoming an issue. They use PHP and with an old and rather inflexible framework, so even though changing how the database is used is possible, it's not easy and having database routing in the application code isn't a very good idea either.
As you've heard, MaxScale was recently released, and we'd love for you to try it out and let us know your thoughts.
Anders Karlsson and Ivan Zoratti have written some excellent posts on downloading and setting it up, so if you're intersted in that, please see their respective posts for quick, detailed instructions.
I have spent some time thinking about and working on a project that went public on GitHub at the beginning of this year. That project is called MaxScale and is primarily a proxy server for MySQL/MariaDB databases, although it can be something much more than this. The obvious and often asked question is why do we need another proxy? I want to try to give you a flavor for what MaxScale is and why I think there is a need for a tool like MaxScale.
The architecture of MaxScale makes it different from your average proxy

Introduction
Drupal is one of the most popular Content Management Systems (CMS) and is used increasingly in high-visibility sites, such as www.whitehouse.gov. This has brought a lot of attention on how to get the most performance out of Drupal and how to improve the availability of such sites. In this blog series I'll take you through the basics and on through to designing your own HA Drupal site.
But first, we need to understand what the challenges are in getting Drupal (or indeed any CMS) working on multiple servers in such a way as to ensure high availability and performance.
Background: SkySQL is a distributed company. Nearly all of us work from home. To be productive, we need to emulate the best aspects of collaborating as if we were working next to one another. Given that nearly all of us had worked under similar distributed conditions at MySQL AB, we knew what we were getting into when we were founded. Obviously, we wanted to learn from our past experiences when making our choices for tools and processes.
This post is about a fairly technical detail of how Galera works. I'm writing it down in preparation for testing this feature so that I can agree with Alex whether to file a bug or not. I'm sharing it on my blog just in case someone else might benefit from learning this.
Galera 2.0 introduces rolling schema upgrades. This is a new way to do non-blocking schema changes in MySQL.
As the name suggests, it is done as a rolling upgrade. Having seen clusters doing rolling upgrades before, I assumed this is what happens:
The slides from last week’s talks I (co-)presented at Percona Live and Linuxcon Europe are now available from our web site.
If you run (or plan to deploy) high availability clusters — with or without DRBD — you might find a new section on our web site handy. Our Technical Guides collection is a compilation of LINBIT expert HA knowledge, which we’re opening up to everyone.
Yes, this also includes PDF versions of the DRBD User’s Guide and the Linux-HA User’s Guide.
More Technical Guides will be added as we go along. LINBIT Cluster Stack support customers will receive new Tech Guides approximately one month before they pop up on …
