For years it was very easy to defend InnoDB’s advantage over competition – covering index reads were saving I/O operations and CPU everywhere, table space and I/O management allowed to focus on database and not on file systems or virtual memory behaviors, and for past few years InnoDB compression was the way to have highly efficient OLTP (or in our case – SGTP – Social Graph Transaction Processing) environments. Until one day (for some it came sooner, for others later)…

InnoDB team announced that it will change how it is going to do compression in the future and that old ways (that we rely on) will be all gone. I’m not exactly sure if there was any definite messaging on the future of existing methods, but Oracle in public will never put out a roadmap, and there’s lots of uncertainty involved then. Unfortunately, with this uncertainty, we probably lost quite some momentum in InnoDB engineering efforts (we don’t get to see some …

This is an incomplete fragment from 2011. Figure its worth publishing this now, considering MariaDB is likely to get groonga in the near future. The groonga team have released MariaDB 10.0.6 binaries as well. This is all part of the mroonga project.

These were my quick notes from the groonga talk at the O’Reilly MySQL Conference & Expo 2011. I haven’t tried it yet (and don’t know if it really is faster than Sphinx), but its something I definitely want to play with. Maybe even get a MariaDB tree going.

groonga is a fulltext search library for cloud & web.

groonga is easy to embed & is scalable. It is written in C.

Team MariaDB will be at the Percona Live MySQL Conference & Expo 2013, held in Santa Clara from April 22-25 2013. We will also be at the SkySQL Solutions Day held on April 26 2013 at the same venue, the Hyatt Santa Clara. We have talks, a booth in the DotOrg Pavilion, have a BoF and we’re participating in the passport program.

Team MariaDB talks:

1. (Monday) Advanced Query Optimizer Tuning & Analysis, a tutorial by Sergei Petrunia & Timour Katchaounov
2. (Tuesday)  …

The journey to the Hotel in Santa Clara took me something like 16 hours. It was long, arduous and at times despairing, but was it worth it? Absolutely! I made the epic journey with my Pythian (and former Nokia) colleague Andrew Moore, and once at the conference we met up with more members of our [...]

Day 1 is the first official day of the Percona Live MySQL Conference. It began with two mini keynotes by Peter Zaitev and Baron Schwarz of Percona talking about the history of MySQL and his beginnings in the open source movement, respectively. It was very nostalgic, and I’m sure it brought a tear to a few people’s eyes.

Following the dynamic duo was full keynotes by Mårten Mickos (Eucalyptus Systems) on “Making LAMP a Cloud” and Brian Aker (HP) on “The New MySQL Cloud Ecosystem”. To be honest, I found the full keynotes to be quite disappointing. For me, the keynotes speeches should be about a topic that is visionary or notable in some way. What I got from the keynotes were:  MySQL is good, MySQL is growing, let me show you my product around MySQL, and buy/use my product. They felt far more like glorified sales pitches.

I remember that at the last conference I attended, SXSW Interactive, the keynotes by Ray …

Day 0 of the MySQL Conference was a day unlike any other day. It was, in fact, tutorial day. While regular days of the Percona Live MySQL Conference feature 50 minute sessions, usually split into a 40 minute talk and a 5-10 minute question period, tutorials are 3-hour-long sessions (with a generous 10 minute break in the middle for those that wish to go to the WC) that provide an in-depth dive into some aspect of MySQL. Due to the length of the tutorials, they are more in-depth and technical than individual sessions can be, but at the same time, we are limited to 2 tutorials slots per day instead of the 5 for sessions.The tutorial schedule for the conference is located here, and with so many good ones, it was hard to choose which one(s) to go to.For the morning session, I attended Peter Zaitev’s tutorial entitled “InnoDB and XtraDB …

MySQL Cluster Performance Tuning ——————————————- In this session we will look at different tuning aspects of MySQL Cluster. As well as going through performance tuning basics in MySQL Cluster, we will look closely at the new parameters and status variables of MySQL Cluster 7.2 to determine issues with e.g disk data performance and query (join) [...]

In about 4 hours at 2PM PDT, I’ll be giving my talk “Security Around MySQL” at Ballroom A at the Percona Live MySQL Conference 2012. It’s a summary and guide of practical and easy-to-implement security tips around MySQL and the application. These tips were all gleamed from my years at start-ups (some of which I worked on and some which I founded) and from my experience at Pythian.

The details are here:  http://www.percona.com/live/mysql-conference-2012/sessions/security-around-mysql.

A panel on “Future Perfect: The Road Ahead for MySQL“, by Brian Aker (HP), Paul Mikesell (Clustrix), Sundar Raghavan (Amazon), Slavik Markovich (McAffee), and Ori Hernstadt (Akiban).

If there’s one common theme to this panel and  this whole conference, it’s: “We’re hiring!” It is amazing how much talent there is at the conference this year, and yet, it isn’t enough. Pythian is hiring as well of course: http://bit.ly/pythianjobs.

There was an interesting distinction between the mindset of Oracle and of MySQL made by Brian Aker: database as a service, which is something MySQL seems to be getting to. It comes with its own problems, especially around trust levels, which will lead to more thinking around data security (rather than just database security).
