Ghosts of MySQL Past: Part 2

This continues on from my post yesterday and also contains content from my 2014 talk (view video here).

Way back in May in the year 2000, a feature was added to MySQL that would keep many people employed for many years – replication. In 3.23.15 you could replicate from one MySQL instance to another. This is commonly cited as the results of two weeks of work by one developer. The idea is simple: create a log of all the SQL queries that modify the database and then replay them on a slave. Remember, this is before there was concurrency and everything was ISAM or MyISAM, so this worked (for certain definitions of worked).

Past, present and future of MySQL and variants: 2014 video

Early this month I spoke at in Perth, Australia, where I presented “Past, Present and Future of MySQL and variants.”

Here’s my presentation in its entirety. Please let me know if you have any questions or comments. ( is widely regarded by delegates as one of the best community run Linux conferences worldwide.)

The post Past, present and future of MySQL and variants: 2014 video appeared first on MySQL Performance Blog.

My lca2014 talk video: Past, Present and Future of MySQL and variants

On last Wednesday morning I gave my talk at 2014. You can now view and download the recording of it here:

(hopefully more free formats will come soon, the all volunteer AV team has been absolutely amazing getting things up this quickly).

MySQL and PostgreSQL Cloud Offerings – 2012 miniconf talk by myself and Selena

Selena and I gave a talk on the various issues of running databases “in the cloud” at the recent in Ballarat. Video is up, embedded below:

LCA Miniconf Call for Papers: Data Storage: Databases, Filesystems, Cloud Storage, SQL and NoSQL

This miniconf aims to cover many of the current methods of data storage and retrieval and attempt to bring order to the universe. We’re aiming to cover what various systems do, what the latest developments are and what you should use for various applications.

We aim for talks from developers of and developers using the software in question.

Aiming for some combination of: PostgreSQL, Drizzle, MySQL, XFS, ext[34], Swift (open source cloud storage, part of OpenStack), memcached, TokyoCabinet, TDB/CTDB, CouchDB, MongoDB, Cassandra, HBase….. and more!

Call for Papers open NOW (Until 22nd October).

HOWTO screw up launching a free software project

Josh Berkus gave a great talk at 2010 (the CFP for 2011 is open until August 7th) entitled “How to destroy your community” (lwn coverage). It was a simple, patented, 10 step program, finely homed over time to have maximum effect. Each step is simple and we can all name a dozen companies that have done at least three of them.

Simon Phipps this past week at OSCON talked about Open Source Continuity in practice – specifically mentioning some open source software projects that were at Sun but have since been abandoned by Oracle and different strategies you can put in place to …

Head on over to and check it out!

You’ve got until August 7th to put in a paper, miniconf, poster or tutorial.

Things I’d like to see come from my kinda world:

  • topics on running large numbers of machines
  • latest in large scale web infrastructure
  • latest going on in the IO space: (SSD, filesystems, SSD as L2 cache)
  • Applications of above technologies and what it means for application performance
  • Scalable and massive tcp daemons (i.e. Eric should come talk on scalestack)
  • exploration of pain points in current technologies and discussion on ways to fix them (from people really in the know)
  • A Hydra tutorial: starting with stock Ubuntu lucid, and exiting the tutorial with some analysis running on my project.
  • Something that completely takes me off …

Storage Miniconf Deadline Extended!

The organisers have given all miniconfs an additional few weeks to spruik for more proposal submissions, huzzah!

So if you didn’t submit a proposal because you weren’t sure whether you’d be able to attend LCA2010, you now have until October 23 to convince your boss to send you and get your proposal in. 2009 wrap-up (incl Open Source Databases Mini-conf): Day 0-1

It’s no secret that I love My first was 2003, in Perth and I’ve been to every one since (there are at least two people who’ve been to every single one, including CALU as it was called in 1999).

I’ve been on the board of Linux Australia for some insane proportion of the years since then (joining in 2003). Linux Australia is the not-for-profit community organisation that puts on It’s all volunteers and amazingly enough we have more than one group of people wanting to put on each year!

This year, we Marched South to Hobart.

Here I detail what I saw, what I wish I …

OurDelta at

Arjen & Monty @ LCA2009 in Hobart

I did a couple of sessions on OurDelta at the database miniconf: an overview of the project, a short delve into the features, and a “hacking the mysql server for dummies” which was found of particular interest. It’s a pity that session didn’t get accepted into the MySQL conference, it even had MySQL-uberguru Antony Curtis as co-speaker.

In the hacking talk in Hobart, I showed people the basic infrastructure of the source tree, then going through one particular patch and which changes it makes inside the server (and why). This is an excellent way to learn, as patches have a neat limited scope yet they do something significant. The good news is that the sessions were recorded, so when the LCA team finishes transcoding the hundreds of sessions we might be able to put ours up here!
