MySQL Camp T-Shirts

For those that attended the MySQL Camp at Google HQ late last year you may have seen me with my own T-Shirt designs. A number of people inquired about getting them. I’ve finally got around to make them available online, so anybody that would like one can order online.

There are two different shirts. If you want your name on the shirt, you need to make sure you choose the correct one.

  • Early Adopters - For those that were the first 48 that signed up, your name as well as position and company are on the shirt.
  • The Herd - For everybody that registered on the website, your name is on the shirt.

Ok. I’ve …

Pluggable Storage Engines - What is the potential?

I started this post a month ago, but after Kaj’s discussion on the same topic at the MySQL Camp I figured it was time to post.

I had dinner with a friend recently (a very smart friend), and our conversation lead him to ask “What’s different with MySQL?”. One of the things I tried to describe was the “Pluggable Storage Engine Architecture” (PSE) potential for the future that I expect will set MySQL apart from all other Open Source and even commercial databases.

Here are some details of the example I tried to provide, given somebody who understands enough of the general principles of RDBMS’s.

Consider the ability that information (intelligent data) is available within a Relational Database via the appropriate tools and language (e.g. SQL) but it is not physically constrained to Tables, Columns …

The desire for Performance SQL Tips

It seems, people are clammering for a more consolidated help guide for SQL Performance tips.

Jay Pipes at the MySQL Camp ran a session Interactive Top 10 SQL performance Tips. There was plenty of input and discussion, and at the time Sheeri simply typed them into a wiki page for later work.

Well it seems even that rough list is popular at ranking near the top of the Hot List on the front page. I saw it earlier and it was second or third, but didn’t think of taking a screen shot until now, but it’s still high.

I’d say that we could easily …

The MySQL Joust

At our MySQL Camp Jay and Brian pitted off in the Umbrella Joust. Not sure if there was a winner, or a looser, but in the end no blood was split (except Leslie, but that’s another story).

See these and more camp photos at Flickr.

The Falcon!

Some early notes by Brian Aker on Falcon as discussed at the MySQL Camp.

Falcon is a transactional engine MySQL will be introducing. The first discussions were held about 3 years ago with Ann Harrison and about 1 1/2 years ago, MySQL started taking seriously the possibilities.

Falcon is not an InnoDB replacement. It’s a different way of looking at the problem of how it looks at and manages transactions, and how it’s designed. It flips around the way data is stored. Some points:

  • It uses as much memory as possible, like Oracle SGA or InnoDB pool.
  • It has a row cache not a page cache for more optimal memory use.
  • No locking at all. Jim doesn’t believe in it for concurrency control. It has total versioning.
  • Falcon has to keep all changes in memory, so not great for user transactions that may take longer

Day 3 - Memorable Quotes

The final day of the MySQL Camp quotes. See also Day 1 and Day 2.

“Patches on Patches on Patches.” — Jeremy in his Query Profiler patch talk.

“I bagged Jeremy, no I mean I bashed Jeremy and all I got was this badge.” — Sheeri

“You have an enum of ‘Red’, ‘Blue’, and ‘Yellow’, and what is the result if you add 1 five times to the value of the enum.”
— Brian Aker Quiz question. The answer is Blue, and the winner was Taso. Why. You will need to do the certification example, or email me and I’ll tell you.

“High bandwidth opaque identifier” — Chuckie talking about his Unique Internet Id

“So you have until the end of lunch to work out how to start the Instance Manager” — Brian Aker on …

Monty gave us a quick overview of next generation of MyISAM. It is set to include:

  • New data disk format
  • Transaction support
  • multi-versioning
  • row level locking and escalation to table level locks. (interesting)
  • bitmap indexes and new table scanning optimizing indexes with up to 1000x times performance.

No details of time frame were given for delivery, however development is well underway.

Doxygen Project

What the?

Well this is the inheritance diagram of the Item Class in the MySQL 5.1 Source tree, nicely documented using the Doxygen tool as mentioned by Jay in his presentation at MySQL Camp.

Jay started the Community Doxygen Project on the Forge to improve the level of commenting enabling a better platform for the community to contribute MySQL server code changes.

At this early stage David Shrewsbury is working on fine tuning initial documentation examples for QA and review. You can check out the Status Page of automated commenting conversion.

You can see the present documentation of MySQL 5.1 source …

Aussies at Google

My new Google family since I’ve now moved to the US. Ronald, James, Michael, Shona and Kynan (front). James has literally been here in the US only a few days more then me, and he has an amazing Day 1 story.

Apparently there are a reasonable number of Australians now working for Google. Another interesting fact is the male/female ratio is 6:1 which is extremely high in comparison to the IT industry and IT related university studies.

The joys of working at Google

So, mid morning especially after having a heavy and late night drinking with new friends in Palo Alto I was seeking at Day #3 of the MySQL Camp a high-caffeine pick me up drink. Yesterday I had a Bawls, and after enjoying it I was a little concerned that when I returned to New York I would not be able to buy it. You can get it at Think Geek but that’s more complicated then a local supermarket.

So after getting a Googler to get me to the cafe fridge we find out that there weren’t any there. No problem, lets just go this way I’m told. So we start a quick tour of the larger cafe area and another set of fridges but no Bawls, we keep walking, no more again. At this time the recommendation is I should try a Rockstar, but so …
