The last MySQL User Group NL meeting was last Friday. It's always nice to learn about MySQL and meet other MySQL users. There were two presentations: one about MySQL User Defined Functions (UDF's) and one about MySQL TCO. The slides are available from the meetup page.

There are already a number of MySQL events announced for the next few months. I'll only list events in the Netherlands and Virtual events.

It's a long way from Europe to New Zealand, and so I will take a few stops.

On Monday, October 12, 2009* from 7-9 pm at MIT, I will be giving a presentation explaining SHOW ENGINE INNODB STATUS for the Boston MySQL User Group. There is information about foreign keys, transactions, deadlocks and mutexes just waiting to be discovered, and I will show how to decipher the information.

For all those in the Boston area, I hope to see you there! For those who cannot be there, we will video this presentation and make it available online, and post here when the video/slides are up.

*Yes, I realize that this is a bank holiday in the US.

At the July MySQL User Group, Eric Day and Patrick Galbraith spoke about Drizzle, a lightweight, microkernel, open source database for high-performance scale-out applications, and Gearman, an open source, distributed job queuing system.

The slides can be downloaded from http://www.oddments.org/notes/DrizzleGearmanBoston2009.pdf.

The first hour of video, where Eric and Patrick talk about Drizzle, is at http://www.youtube.com/watch?v=hi4cGzFlcuU, and below:

The second part, about 1.5 hours, where Eric and Patrick talk about Gearman, and then illustrate Gearman and Drizzle working together in a custom search

The July meeting of the Boston MySQL User Group will feature Eric Day, a prominent Drizzle developer, talking about Drizzle and Gearman:

In this talk we will discuss two growing technologies: Drizzle and Gearman.

We will explain what the Drizzle project is, what we aim to accomplish, and an overview of where we are at. We will also be introducing the fundamentals of how to leverage Gearman, an open-source, distributed job queuing system. Gearman’s generic design allows it to be used as a building block for almost any use - from speeding up your website to building your own Map/Reduce cluster. We will tie Drizzle and Gearman together and demonstrate how they work in a custom Search Engine application.

As many may probably know, Boston is one of my favorite towns. I have been in love with this town since my first visit in 1990, and in every subsequent trips I have always been enchanted by the town itself and by the kindness I was shown by its people.
I am also very fond of the Boston MySQL User Group, and its organizer, Sheeri K. "Super Hero" Cabral.

I want to show my personal appreciation for Boston by sponsoring the MySQL User Group for one year. I am doing that with my own money, without involving my company.
You can also donate for a MySQL user group, if you want, using the Technocation fund.
You can specify

In the wake of Meetup.com changing their sponsorship agreements, Technocation, Inc., an international not-for-profit group, has set up a fund for user group sponsorships. You can use the button below to donate any amount of money in US funds via PayPal:

(all monies sent through that button will be earmarked as a directed donation to the “User Group Fund”. In the interest of not cluttering up this blog post with a Donate button for each currency, you can use PayPal to send funds in *any* currency to “donate@technocation.org”. Just be sure to specify if you want the money to go to specifically to the User Group Fund.*)

Note that meetup.com’s fees are $144 per year ($12 per month).

Four years ago, MySQL and Meetup.com entered into an agreement. I have no idea of

The session at the Boston MySQL User Group was very enjoyable. There was a full room, and the presentation was followed with attention and curiosity.
The slides I used for this presentation include the deck used by Allan Packer and Mikael Ronström at the MySQL Conference 2009, followed by a testimony of my own experience with 5.4.
Here is the final deck: MySQL 5.4 theory and practice

While preparing the slides, I realized that, for the first time, we have a product that allows a painless performance gain. Unlike all the tuning and technological improvements

We’ve had MySQL meetup’s organised thanks to mysql.meetup.com for years now, and its sad to see the relationship end in about a fortnight. Never fret, because it seems that Facebook can do all that, and more.

Migration

If you’re the meetup organiser, and you checked the Members list, or even attempted to download it, you’ll be disappointed. You get a CSV file, with the name of the person, some other metadata, if they’re on the mailing list (chances is yes to all), and the URL of the member profile. What’s missing? An email address.

So while its nice to have a CSV copy of the member list, it will not assist you in any migration, whatsoever. Totally data lock in :-(

Mailing list/message board

Keep in mind that you’ve got mailing lists and message boards on meetup.com.

The MySQL Boston User group will meet on May 11 at 7pm.
I will speak about my experience using MySQL 5.4, with some general information on the release.
BTW, you know that there has been some trouble about MySQL meetup groups. We are looking into the matter, and we will release information as soon as possible. For now, I can tell you that the current agreement between MySQL and Meetup is valid at least until June 10, 2009.

The bad news is that whatever agreement MySQL AB had with Meetup.com has ended. As per the wiki at http://forge.mysql.com/wiki/How_to_create_a_user_group:

MySQL AB has an agreement in place with meetup.com to cover the organizer fees. Simply click at the link at the top of the meetup.com page to request your electronic voucher so you can become an organizer.

Unfortunately, this agreement has ended, so there’s going to have to be a more manual process to get MySQL to sponsor the meetup groups. At its cheapest, a year of meetup.com is $144.

The good news is that Giuseppe and Dups (as well as the local Sun/MySQL folks in Boston who also sponsor the pizza and soda we have) have expressed that they are dedicated to sponsoring these user groups, so

I am passing this along — I am not sure if most folks reading this can make it, as it is last-minute and in the Boston area, but I figured I’d let people know that the New England Database Society exists. It’s free, sponsored by Sun (and has been for years, long before Sun bought MySQL), and is hosted by my college database professor, Mitch Cherniack. (To that end, I should probably make sure to promote the Boston User Group here more often! I keep forgetting…)

You can find information on how to be a part of the mailing list at http://www.cs.brown.edu/sites/neds/

The next New England Database Society will be held on Friday, March 27 and the speaker is Christian Jensen of Aalborg University.

At the March Boston MySQL User Group meeting, Jacob Nikom of MIT’s Lincoln Laboratory presented “Optimizing Concurrent Storage and Retrieval Operations for Real-Time Surveillance Applications.” In the middle of the talk, Jacob said he sometimes calls what he did in this application as “real-time data warehousing”, which was so accurate I decided to give that title to this blog post.

The slides can be downloaded in PDF format (1.3 Mb) at http://www.technocation.org/files/doc/Concurrent_database_performance_02.pdf. The 54 minute video can be downloaded (644Mb) at http://technocation.org/node/693/download or streamed directly in your browser at
