MySQL :: Developer Zone Quick Polls
+0 Vote Up -0Vote Down

I don’t get to the MySQL Developer Zone main page often enough. In thinking about what pages I view everyday or regularly, it doesn’t rate as high as Planet MySQL, MySQL Forums or even the MySQL Forge.

I was most dissappointed in the results of a recent poll What did you think of the 2006 Users Conference?. The top response was I had no idea there was a Users Conference. That’s not good to see this.

An interesting poll What are you most looking forward to at the MySQL Users Conference (April 24-27)?,

Finally back home after some R&R at Yosemite before leaving the US. In conclusion, to sum up my experience of the 4th Annual MySQL Users Conference “Excellent”.
Here’s my take. Friends, Functionality & New Features, the Future.

Friends

I’ve used MySQL (http://www.mysql.com" target="_blank) now for over 6 years, and full time for a number of years, yet I’ve only become active in the MySQL community, particularly Planet MySQL in the past 6 months. Over that time, I’ve read a lot from members, and heard from many people. It was great at the conference to meet many of these people for the first time. The list includes: Community Members -

MySQL Stored Procedures Performance
+0 Vote Up -0Vote Down

Another one of the sessions at the MySQL Users Conference I attended was Tuning MySQL5 SQL and Stored Procedures by Guy Harrison from Quest Software. A global company with 6000+ customers.

Guy has written a number of Oracle Performance Books in the past. His work now is on the “Spotlight” product family - Database diagnositic tools converting data to graphical representations. For these products, MySQL 5 and InnoDB only is necessary, simply due to accessing the right internal information for presentation. There are Freeware MySQL product downloads.

In this presentation he stated, nothing he was talking about specifically was relatively new. He did make quite a funny comment, “He is

I didn’t take any photos myself at the MySQL User’s Conference. In reflection, perhaps I should. I did make it into some photos however. A few of them here.

Mark Shuttleworth

Thursday’s Keynote speaker at the MySQL Conference was Mark Shuttleworth talking on The Ubuntu Project: Improving Collaboration in the Free Software World.

Ubuntu from Canonical Ltd is fastly becoming one of the most popular Linux Distributions, based on Debian. Here were some notes from his presentation. Mark had some really powerful one or two line slides that typified both his presentation intention and the goal of Ubuntu.

My MySQL Conference Presentation
+0 Vote Up -0Vote Down


My talk at the MySQL Users Conference went well. MySQL For Oracle Developers was part of two talks, the second was by Mark Leith on MySQL For Oracle DBA’s.

I had a number of positive comments from attendees, including Ken Jacobs of Oracle who also contributed some valuable information in comparision of UPDATE/DELETE ORDER BY/LIMIT statements I was unaware of.

You can download my paper here.

My slides, like many talks just scratched the surface in the alloted. I’ve been working on additional reference material, a work in progress is

Hacking MySQL Source improvements
+0 Vote Up -0Vote Down

Further to my earlier post Hacking MySQL Source (in a good way) in which I was having a compilation problem when re-compiling MySQL source (i.e. tt worked the first build, but failed on subsequent re-compiles, even with no changes).
I’ve been able to solve my re-compiling issue, with special thanks to Jan Kenschke of MySQL AB, who was near during the MySQL Quiz Show.

As suspected, there is no need to re-run the ./BUILD/compile-pentium-debug command as this cleans, a simple make command is sufficient (I needed to confirm no other command args where needed). By doing this, it also better highlighted the actual error, where previously is wasn’t. I didn’t keep a copy of the error, but in effect I needed to do the following in

Contributing to the MySQL Community
+0 Vote Up -0Vote Down

Everybody can contribute to the MySQL Open Source Community. Here are some ideas:

  • You can start with completely a MySQL Conference Survey form (those forms that we are all avoiding).
  • You can download, evaluate and test newer versions of MySQL Products.
  • You can contribute to the MySQL Forums to ask questions and even give answers.
  • Log Bugs & Enhancements on MySQL Products.
  • Write about your experiences with MySQL (http://www.mysql.com" target="_blank) in a Blog and add your Blog to PlanetMySQL. With now over 100 feeds, if everybody wrote something about MySQL in the next year, we would have over 1000 feeds next conference.

Stumping a MySQL Guru

At the MySQL User Conference - MySQL Quiz Show we were asked to Stump a MySQL Guru. Well I submitted a few questions, and the first one stumped the guru, being Jeremy Cole, and my prize was a MySQL tee-shirt.

The Question: What are the current supported languages of the GRT Environment used in the MySQL GUI products?
The Answer: Lua, C, C++, Java, Python and PHP

Extracting User SQL Queries from a MySQL Server

Joe Kottke from FeedBurner in his MySQL Conference presentation today FeedBurner: Scalable Web Applications Using MySQL and Java mentioned a novel way of extracting SQL Select Statements from a MySQL Server.

The obvious MySQL ways include SHOW [FULL] PROCESSLIST, the Slow Query Log, and the General Query Log. In 5.1 you also use the INFORMATION_SCHEMA.PROCESSLIST.

HackFest B: Creating a New SHOW Command by Brian Aker at the MySQL Users Conference

Brian stepped through the steps for those attending to modify and deploy new functionality in the mysql server. Cool. The end result I would consider for an experienced developer as relatively easy (after avoiding the pitfalls).

NOTE: I wasn’t able to complete this successfully during the session, but I’ve posted this, so hopefully the input and review of others can help in overcoming the current issues. See Outstanding Issues throughout my notes.

Our goal: Produce a new command SHOW CONFERENCE;

PBXT - The MySQL Community Transactional Storage Engine
+0 Vote Up -0Vote Down

In having a discussion with Paul McCullagh (the creator of PBXT transactional storage engine) and Taneli Otala MySQL AB (http://www.mysql.com" target="_blank) CTO after the keynote presentation at the MySQL User Conference, Taneli made the following comment (paraphrased and reproduced with permission).

“I talk about PBXT in discussions shamelessly. The development of PBXT was excellent timing in the MySQL community landscape”.

It was an excellent commendation that MySQL AB management considered so highly the contributions from the community. As mentioned in the opening keynote, MySQL with the Storage Engine API with MySQL 5.1 has great potential to expand what options are available to user of MySQL.

Good work Paul. I like many others wish you the best in your continued development and contribution.

Improvements in SHOW STATUS
+0 Vote Up -0Vote Down

It just dawned on me as this topic was mentioned in a MySQL Conference presentation yesterday in a manual process. So my thought is, why can’t the following functionality be added to the MySQL server.

My request for two new extensions to the SHOW STATUS command.

SAVE STATUS - This enables the current SHOW STATUS to be saved (or more specifically cached), you can only keep one copy per server instance.

DIFF STATUS - This shows the difference between the current SHOW STATUS and the last saved show status from the SAVE STATUS command.

This would quickly, easily and interactively via a mysql prompt enable a DBA to see the state of change in a more condensed form. The syntax may need to cater for Session/Global scope, and of course would need to be appropiately named, my examples is just an idea.

Of course you can write an easy script that

Could not have said Agile better myself

I’ve just attended Scott Ambler’s presentation on Agile Database Techniques: Data Doesn?t Have to be a Four-Letter Word Anymore at the MySQL Users Conference.

There is so much content on the topic, it’s impossible to present so much information in a short 45 minute session. I can speak with authority in regards to the same problem of condensing so much content given this issue with my own presentation MySQL for Oracle Developers.

I ask this question. Why is common sense considered such a radical approach? I state this because Agile Methodology approaches in so many

Opening Conference Keynote
+0 Vote Up -0Vote Down

Mike writes a good summary of the MySQL Conference opening keynote State of the Dolphin: Interview with Kaj, Monty and David of MySQL.

I’d like to add just two comments.

Firstly, it was great to see community awards to Giuseppe, Roland, Marcus and Rasmus. Well done!

Second, it was a great thing to see on the slides a reference to Paul’s PBXT Transactional Storage Engine. A MySQL storage engine from the community. I’ve had a chance to meet Paul and have a number of great discussions with him. I wish him all the best, and I’m happy to contribute what I can to see his engine make it into the MySQL product in the future.

Bootstraping

Tuesday’s Keynote speaking from the MySQL Users Conference including a presentation from Greg Gianforte of RightNow Technologies on “Bootstrapping: Starting an Open Source Business With Almost No Money!Read More.

Taking directly from Greg’s presentation, here are some key points for bootstraping that meant something to me.

  • Sales is Job #1
  • Don’t spend Beyond Your Means
  • There Is Always Another Way
  • What is Your Noble Purpose?

Some great points. In summary, not having funds should not be an excuse, find another way . You just need to think creatively. I agree completely, thinking creatively is something I do well. Immerse

My First BoF - MySQL GUI?s
+0 Vote Up -0Vote Down

Last night, I attended Mike Zinner’s presentation of MySQL GUI’s, most specifically MySQL Workbench. In summary I was very impressed with the current work, and the future potential. I’ve been waiting for now about a year to get access to full strength MySQL Workbench (it has been available for some time, but still in early development), having previously used DB Designer for MySQL Data Modelling. One of the limitations is finding a quality tool that runs under Linux. Well MySQL workbench will satisfy this and far more in the future.

A quick summary of some of the glossy features.

  • Reverse Engineering of schemas from multiple input sources including MySQL, Oracle, MS SQL Server.
  • Synchronisation with a MySQL Database.
  • Quick Re-Synchronisation.
  • Full GUI tools and features for

Save the Falcon!
+0 Vote Up -0Vote Down

While many people will be blogging about the conference sessions and MySQL features, functionality and sessions, I thought it would be important to raise awareness of the creativity of developers often lost during the product lifecycle.

I met at the Speakers Function last night Jim Starkey, the founder of Netfrastructure, Inc, a company aquired by MySQL recently. At the conference was the official launch of a new transactional storage engine to be included in the MySQL 5.1 release is codenamed “Falcon”.

Too often, the flare and creativity of products, and also the initial history is lost when it reaches the marketing department of an organisation. In this case, after talking with Jim, we decided it was important to ensure the name “Falcon” remains. Why should the name conform to something generic, and quick frankly boring. So please join me.

Save The Falcon!
