Problems of Oracle's MySQL as an Open Source Product

In my previous summary blog post I listed 5 problems I see with the way Oracle handles MySQL server development. The first of them was that "Oracle does not develop MySQL server in a true open source way" and this is actually what I started my draft of that entire blog post with. Now it's time to get into details, as so far there was mostly fun around this and statements that MariaDB also could do better in the related Twitter discussion I had.

So, let me explain what forces me to think that Oracle is treating MySQL somewhat wrong for the open source product.

This Week in Data with Colin Charles 41: Reflecting on GitHub’s Contribution to Open Source Database

Join Percona Chief Evangelist Colin Charles as he covers happenings, gives pointers and provides musings on the open source database community.

Some big news out from Microsoft about their acquisition of GitHub for $7.5 billion. GitHub hosts many projects, including from the MySQL ecosystem, but maybe more interesting is that their DBA team is awesome, give great talks, and are generally prolific writers. Some of the cool tools the MySQL world has gotten thanks to the excellent team include (but are not limited to): ccql, gh-ost for triggerless online schema migrations, and Orchestrator which is a GUI-based High Availability and …

GitHub acquired by Microsoft

Microsoft has just acquired GitHub for $7.5bn.  Good or bad?

Injected VC capital was $350m, so ROI for the VCs = 21.4x = very happy VCs.

Microsoft has done excellent work on OSS software in recent years, including on the Linux kernel, PHP, and many others.  Just like Oracle continues to put very good effort into MySQL after the Sun Microsystems acquisition many years ago.

But Microsoft is not an Open Source software company. The open source development model is not something they have built into their business “DNA” – processes (actually many companies that only do OSS haven’t got that either). So why GitHub? Combine it with LinkedIn (acquired by Microsoft earlier), and you have developers’ resumes. That’s valuable. It’s a strategically smart move, for Microsoft.

Will GitHub users benefit, and if so, how?

Well, I expect there’ll be more hoovering of “useful” (meta)data by a …

Community contributions to MariaDB

One of the goals of the MariaDB Foundation is to help new contributors understand the source code and to lower the barrier for new participants. One way to measure this is to look at the number of pull requests received and accepted, as these mostly reflect community contributions. The figures below are for the main […]

My First Steps with MariaDB ColumnStore

This is a "Howto" kind of post, and some speculations and historical references aside, it will show you how to build MariaDB ColumnStore (current version 1.0.9) from GitHub source, how to install and configure it for basic usage, as well as how to resolve some minor problems you may get in the process. Keep reading and eventually you'll get the real Howto below :)

Practical Orchestrator, BoF, GitHub and other talks at Percona Live 2017

Next week I will be presenting Practical Orchestrator at Percona Live, Santa Clara.

As opposed to previous orchestrator talks I gave, and which were either high level or algorithmic talks, Practical Orchestrator will be, well... practical.

The objective for this talk is that attendees leave the classroom with a good grasp of orchestrator's powers, and know how to set up orchestrator in their environment.

We will walk through discovery, refactoring, recovery, HA. I will walk through the most important configuration settings, share advice on what makes a good deployment, and tell you how we and others run orchestrator. We'll present a few scripting/automation examples. We will literally set up …

My First Steps with MariaDB 10.2 and RocksDB Storage Engine

Last year I started to explore MyRocks, that is, RocksDB used as a storage engine with MySQL. So far I had to use Facebook's MySQL 5.6 to do this. I could try to use some specific development branches of MariaDB (or maybe even Percona Server) for this, but I preferred to wait until the engine is included into a main branch by the company I work for. Recently this happened, and now you can get RocksDB loaded and working in main MariaDB 10.2 branch. In this blog post I am going to explain how to build it from source and do some basic checks.

I was updating my MariaDB local repository on my Ubuntu 14.04 netbook, with 10.2 branch already checked out (do git checkout 10.2 if …
