Virident Systems and Sun Microsystems, Inc. today announced the GreenCloud™ Server for MySQL, a new server which brings ‘in−memory’ computing on an exceptional scale to Sun Microsystems' MySQL™ database. The new server was launched today at the 2009 MySQL Conference & Expo, where Virident is a Diamond Sponsor. Vijay Karamcheti, Virident CTO and Cofounder, will deliver a Keynote Address to the conference on Wednesday at 8:30AM entitled, “Extreme Performance and SmartScaling MySQL with Storage Class Memory Servers”.

While Zack covered the storage engine and appliances sessions pretty well, I feel he’s missed out on a few important new engines (or engine related talks):

• DDEngine will be represented, speaking about Automated data versioning with a storage engine
• Long time MySQL Community Member Beat Vontobel, will be presenting on the SeqEngine, in Solving Common SQL Problems with the SeqEngine
• Kazuho Oku, from Cybozu Labs in Japan, will be talking about Q4M, a queuing engine for MySQL. Mixi.jp uses it for their Twitter like service, so I’d …

Sun Microsystems and Oracle Corporation announced today they have entered into a definitive agreement under which Oracle will acquire Sun common stock for $9.50 per share in cash. The transaction is valued at approximately $7.4 billion, or $5.6 billion net of Sun's cash and debt.

I’ve just successfully configured Drizzle with the PHP Extension and successfully retrieve data to present on a web page.

Qudos to Eric Day for his work. I was able to identify a problem with the current tar release, and a quick confirmation on #drizzle at IRC confirmed a fix had already been commited.

I’m looking forward to evaluating WordPress and Drupal, two popular and common LAMP stack applications that run on MySQL, and to provide any feedback to the community for future support of Drizzle.

I'm in Santa Clara since yesterday, at MySQL Users Conference.

This will be my fifth conference: I missed only one since 2003. I was supposed to come as a guest, but my friend and colleague Dmitri didn't get a US visa, so I am speaking in his stead. Me and Peter Gulutzan will present new all-engine foreign keys. Oh.

So I'm working from Hyatt. It's a great sunny day, the air here is clear and fresh, and everybody is enjoying the weekend.
Well, as mentioned, except me, and maybe Drizzle developers, who already started Drizzle developer conference :)

Musing about this all, I took a step back, and thought: so typical of me:

It's time for the MySQL User Conference now in just a day or so, I have my talks ready, and I been rehearsing them and doing some final editing last week. Except for all the good talks, and meetings with old friends and MySQL expert from inside and outside of Sun, I am also excited to see so many cool things in the Expo.

Most prominent there is the new Storage Engines, like Virident, Kick Fire and InfoBright. Also, we'll see what MySQL has up it's sleves this year (no, I do not know, this will be a surprise for me also). There are many more Storage Engines to look at, including the InnoDB plugin.

A theme here seems to be performance, quite clearly, so we'll …

This is the second part in in the series of posts about scaling Drupal stack. The first part can be found here.

GLB has been fixed to support unlimited connections and now I can benchmark Drupal stack cluster on large EC2 instances. What I'm looking for here mainly is how much Galera synchronization overhead affects performance here. With small instances everything was pretty much clear: single core hindered by Xen was an easy traget, and scalability was predictably linear. Large instance is dual core, and Xen interference is minimal, Galera synchronization and serialization effect must be more pronounced. How desperately bad is it?
We'll start with looking at HTTP load "elasticity" on large EC2 instance:

Users   Throughput      Latency         Errors
        (req/min)       (ms, median)    (%) …

Despite an annoying 3 hour flight delay from Heathrow (and no, I wasn’t connecting there, I was leaving from there), I’m here in San Francisco and Santa Clara again ready for the MySQL User Conference 2009.

I obviously have my four presentations to get through, and there will be plenty of other stuff going on at the conference both in terms of other presentations, the show floor, the booths, and the Birds of a Feather sessions (which are terrific fun).

But mostly, I see the UC2009 as the best opportunity to meet up with both other MySQL/Sun people, our customers, and the community at large and talk about the thing we are all passionate about – MySQL and the technologies surrounding it.

And I don’t care if that sounds goofy. Nothing beats talking to face to face with like minded individuals, and one thing that MySQL – and Sun – seems to engender is an extreme passion about the products we deliver that I don’t …

After a long and uneventful flight from HAM to SFO via FRA, I arrived safely in Santa Clara yesterday. Today we spent the day in San Francisco, for some sightseeing (Downtown, Chinatown, Pier 39 and Fishermen's Wharf) and a bit of shopping. It was a very nice and sunny day, the sunlight helped a lot with getting over the jetlag for a while.

But now I'm pretty tired - I look forward to meeting friends, colleagues and members of our community at the …
