More details about SchoonerSQL performance, please!

Xaprb — Thu, 02 Feb 2012 20:37:52 +0000

Schooner has a blog post showing that one node of their product beats 9 nodes of Clustrix’s in throughput. But this reduces everything to a single number, and that’s not everything that matters. If you’ve looked at Vadim’s white paper about Clustrix’s (paid-for) performance evaluation with Percona, you see there is a lot of detail about how consistent the throughput and response time are.

I’d love to see that level of details in any product comparison. A single number often isn’t enough to judge how good the performance is — fast is not the only thing that matters.

I have absolutely no doubts that a single node of Schooner’s product can run like a deer. It isn’t doing any cross-node communication, after all, so it had better be faster than something that blends multiple nodes together into a virtual “single database server.” And I think if the full story were told, it would be a great knock-down drag-out fight. Give us more details, Schooner!

Central Virginia MySQL Meetup has reached cruising altitude

Xaprb — Wed, 01 Feb 2012 03:06:23 +0000

The first Central Virginia MySQL Meetup was a nice little howdy-do, and as a test flight, I think it showed that the bird can get off the ground quite nicely. So, with the generous help of our meeting host Meddius, we’re going to do it regularly on the 3rd Wednesday of every month. The next event is already scheduled — I will be talking about high availability options for MySQL.

I’m interested in having outside speakers. Anyone who’d like to come and present something MySQL-relevant, please feel free to email me, or contact me via the Meetup page with the “suggest a Meetup” feature. If you’re traveling from outside the area, the airport is CHO, and it’s about 30 minutes away. Amtrak is also very convenient. I’m happy to chauffeur you, and can help you find lodging too.

I will not try to steer overly much, but I hope that this turns into a group where people introduce themselves, mention job openings and other news of interest, and so on.

There are also a couple of related meetups nearby that I want to promote: NOVA MySQL at AOL’s headquarters led by Mike DelNegro, DevOps DC at CustomInk’s offices led by Nathen Harvey, and one I haven’t been to yet but hope to attend soon, Shenandoah Ruby Users Group in Harrisonburg near Rosetta Stone’s headquarters, led by John Paul Ashenfelter.

Free webinar Wednesday: verifying replication integrity

Xaprb — Mon, 16 Jan 2012 20:30:26 +0000

Join me Wednesday for a free webinar on using the new Percona Toolkit v2.0.3 to verify replication integrity. If you’re not familiar with this topic, it’s one of those must-do things that no one officially tells you is necessary with MySQL. The new tools in Percona Toolkit 2.0.3 make it much easier and less complicated — and safer — than before. Well worth an hour of your time.

Organize to resist SOPA in DC

Xaprb — Mon, 16 Jan 2012 13:39:51 +0000

If you’re in the DC area, there’s an emergency meeting of the DC Tech Meetup to get involved in advocating against SOPA and PIPA legislation.

If you can’t make it in person, you can use the EFF’s online form to write your representatives about SOPA and PIPA.

Don’t wait until it’s too late. The Internet is a vital part of our freedom. Well-intentioned legislators could damage that greatly while trying to solve problems they don’t understand fully.

High Performance MySQL Third Edition pre-order available

Xaprb — Fri, 13 Jan 2012 16:38:55 +0000

You can pre-order the new edition of High Performance MySQL now on Amazon or via O’Reilly’s website.

Eric Bergen called the second edition “the best MySQL book on the planet“. What will the third edition be called? The best in the solar system? This reminds me of a joke, supposed to be a true story: three pizza restaurants next to each other had signs saying “best pizza in town,” “best pizza in the world,” and “best pizza on this block.”
