Speaking in March 2016

There are a few upcoming speaking gigs this March 2016:

Two talks in London and one keynote in Singapore, while I will also moderate the database track on the last day of the conference as well. I’ve never been to flossUK before, but the schedule looks very interesting and I’m looking forward to it. FOSSASIA is an event I’ve been going to regularly since it was held in varying places (Vietnam, Cambodia, before finally settling down in Singapore) so this is an always exciting time.

Would happily meet you to talk shop, feel free to drop me an email: colin[at]

Eating our own dog food – Running JIRA on MariaDB

A couple of weeks ago we announced that we were moving from a hosted instance of JIRA to our self hosted instance. The main reason was that we hit 2000 active users in the hosted instance of JIRA and that is the upper limit that it  supports. We obviously wanted to allow more people to […]

Amazon RDS updates February 2016

I think one of the big announcements that came out from the Amazon Web Services world in October 2015 was the fact that you could spin up instances of MariaDB Server on it. You would get MariaDB Server 10.0.17. As of this writing, you are still getting that (the MySQL shipping then was 5.6.23, and today you can create a 5.6.27 instance, but there were no .24/.25/.26 releases). I’m hoping that there’s active work going on to make MariaDB Server 10.1 available ASAP on the platform.

Just last week you would have noticed that Amazon has rolled out MySQL 5.7.10. The in-place upgrades are not available yet, so updating …

SCALE14x trip report

SCALE14x was held at Pasadena, Los Angeles this year from January 21-24 2016. I think its important to note that the venue changed from the Hilton LAX — this is a much bigger space, as the event is much bigger, and you’ll also notice that the expo hall has grown tremendously.

I had a talk in the MySQL track, and that was just one of over 180 talks. There were over 3,600 people attending, and it showed by the number of people coming by the MariaDB Corporation booth. I spent sometime there with Rod Allen, Max Mether, and Kurt Pastore, and the qualified leads we received were pretty high. Of course it didn’t hurt that we were also giving away a Sphero BB-8 Droid.

MySQL Contributions status

This post is an update to the status of various MySQL bugs (some with patches) that I’ve filed over the past couple of years (or that people around me have). I’m not looking at POWER specific ones, as there are these too, but each of these bugs here deal with general correctness of the code base.

Firstly, let’s look at some points I’ve raised:

  • Incorrect locking for global_query_id (bug #72544)
    Raised on May 5th, 2014 on the internals list. As of today, no action (apart from Dimitri verifying the bug back in May 2014). There continues to be locking that perhaps only works by accident around query IDs.Soon, this bug will be two years old.
  • Endian code based on CPU type rather than endian define (bug …

High availability with asynchronous replication… and transparent R/W split

In this post, the first one of a Maxscale series, I describe how to use MariaDB’s MaxScale and MySQL-utilities with MySQL Asynchronous replication.

When we talk about high availability with asynchronous replication, we always think about MHA or PRM. But if we want to transparently use the slave(s) for READs, what can we use ?


  • Three MySQL servers, but one has very limited resources and will …

Questions about MariaDB’s bug system

MariaDB recently announced the migration of the JIRA bug tracking system from the current Atlassian-hosted instance to a self-hosted installation to be found at    This likely isn’t a big deal to the community, and MariaDB is being very proactive in coordinating this change in the community – but it’s an opportunity for me to ask a few questions regarding MariaDB’s JIRA usage to which I can’t find answers.  I certainly welcome answers, feedback or clarification from MariaDB staff.

Before getting started, I should say that I appreciate MariaDB – the product, the company, the staff and the foundation.  MariaDB/SkySQL/Monty Programs serve a unique and useful purpose for community, users and staff who prefer …

Loading JSON into MariaDB or even MySQL - mysqljsonimport 2.0 is available

It was a long time since I updated mysqljsonimport or mysqljsonexport and I had a few things I wanted to do with them. This release is significant enough for me to bump it up to 2.0, and the same is in the works for mysqljsonexport. The one big thing that is now implemented is reasonably advanced support for MariaDB Dynamic Columns, and it is actually pretty flexible, allowing you to load a nested JSON object into a MariaDB Dynamic Column. But don't worry, it will still link and run with MySQL if that is what you want to do (but then you will not have the dynamic column features, for obvious reasons),

Download from Sourceforge as usual (yes, I know I am oldfashioned and that I should have put it on github). Also as usual is the documentation in pdf format that is also downloadable separately.
