I do not recall seeing an announcement about it, pancreatitis but I went looking for the videos today and lo and behold, they were up! Forgive me if I missed a post about it….but if you also missed it, here they are:

What are your speaking about at your session?
How InnoDB organizes and stores table data.

Who would benefit most from attending your session?

Froscon, the German Free Software and Open Source conference, is happening again this weekend in University of Applied Sciences Bonn-Rhein-Sieg.

This year we have a MariaDB/MySQL room, C 217, where we can meet, discuss and present MariaDB and MySQL related issues.

I will probably be in the room or at the MariaDB booth most of the time. I welcome people to come to the room with their database problems so that we can try to solve them 'live' (assuming that the Internet is reliable enough).

I will also hold a keynote, How to make money from Open Source today. This includes some information about …

The MySQL Connect content catalog is published, and I’ll be leading a hands-on lab on MySQL Enterprise Features in Practice [HOL9787].  If you have wondered how to get the most out of the features of MySQL Enterprise subscriptions – whether you are an existing Enterprise customer or not – this lab is for you.  We’ll help you understand the benefits of the various components of the MySQL Enterprise subscription as you install, configure, demonstrate and use the …

A week or two ago, I got into a conversation on Twitter about technical debt, and someone shared this superb video by Ward Cunningham (youtube). Here is Ward’s Interview website.

Join 10,000 others and follow Sean Hull on twitter @hullsean.

Waterfall, agile, developer or operations, devops, managers, CTOs… everyone should watch this video, for it cuts to the heart of the challenges we face doing modern software development, in a fast paced and always changing environment.

Though it’s not mentioned in the video, I would argue using an ORM is an expensive form of debt, one that …

In my recent SQL work for a large Swiss bank, I have maintained nested database view monsters whose unnested SQL code amounted up to 5k lines of code, joining the same table over and over again in separate subselects combined via UNION operations. This monster performed in way under 50ms, no matter how we queried … Continue reading The Myth About Slow SQL JOIN Operations →

UPDATE 2013-08-30: Tungsten 2.1.2 was released.

UPDATE 2013-08-23: We have found a few problems that happen when replicating with RBR and temporal columns. We will have to publish an updated bugfix release quite soon.

Tungsten Replicator 2.1.1 is out. Key features in this release are:

• A better installer, of which we have already given a preview in tpm, the multi-master composer. The new installer allows faster and more powerful deployments of both single and multiple masters topologies. And it also allows the next feature:
• Secured communication layer. Now the replicator data and administrative …

I’m excited about this year’s MySQL Connect in San Francisco. It’s bigger than ever, with 3 days of sessions, tutorials, and hands on labs.  We have more MySQL engineers going there than ever before. Looking at the keynote we are preparing, we have a lot of great news, and exciting benchmark numbers to share.

If you have a chance, make sure you join us this year. Learn about the latest MySQL engineering development, and use this opportunity to talk to the MySQL engineers themselves.

Hope to see you there, Tomas

One longstanding complaint I have heard for the past several years, and still hear today, is that Amazon’s Relational Database Service (RDS) does not allow the configuration flexibility as running MySQL in an ec2 instance. While true, this ignores the consistent work that Amazon has done to provide access to the most important configuration variables needed to tune a MySQL instance (after all, how relevant is it for a customer to set bind_address in an RDS instance).

Let’s take a look visually:

MySQL provides 523 options (35 of them NDB specific, so aren’t relevant to RDS), while RDS provides (via the web UI) …
