The MySQL marketplace today is far more complex then simply choosing between a particular version of MySQL that Sun/MySQL produces.
The MySQL server product in general is released under the GNU General Public License (GPL) v2, however you should carefully review the MySQL Legal Policies as a number of exceptions and different license agreements operate for companion tools such as MySQL Cluster, MySQL client libraries and documentation for example.

Looking into the MySQL ecosystem for products, I’ve produced the following categories:

• Sun/MySQL Official Products
  • MySQL Versions
• MySQL Variants
  • Community
  • Enterprise
  …

The March NY MySQL Meetup featured a presentation from Infobright, a data warehousing solution built on the MySQL Product.

With a pitch of “Simplicity, Scalability and low TCO” I became more impressed with the capability to delivery on these as the presentation proceeded. Here are some highlights.

• The company and product has been around for a few years. Infobright started as a compression engine to sit beside Teradata, providing a significant cost saving to clients, and allowing a two way data transfer between Teradata.
• In September 2008, a open source community edition was released, called ICE. (Which I didn’t know)
• The technology is based on a Rough Set theory, a mathematical approach
• Using a …

It seems January and February were just completely taken up by customer engagements. I don't know if it is due to the recession or what, but we who are selling MySQL are just very busy right now. Towards the end of February I finally got on top of my life again, and on the bright side, I took almost a full week off from work, just to get even with all the overtime I accumulated.

This is old news now, but I still want to make a note of these historical events for my own blog too. If you're like yawn... then don't read it. OTOH, seems like I'm in good company commenting on this this week :-)

So some weeks ago we were hit by the surprising news that Mårten will leave Sun, just a few days after …

Dear reader,

In a little over 3 weeks, April 2nd and 3rd, we’re organizing a Pentaho Partner Summit at the Quadrus Conference Center in Menlo Park near San Francisco.

If you are (as the invitation describes) an “Executive, luminary, current or prospective partner from around the world” and if you come over you’ll meet myself, Julian Hyde and perhaps a couple of other architects as well.  That is outside of a host of other interesting people like Zack Urlocker (MySQL) and of course Richard Daley our CEO. We’ll be doing a couple of lengthy sessions on Kettle and Mondrian …

This Sunday I’ll be flying down to the bay area for my final week of work at Concentric. The following week I’ll be starting as a full-time Drizzle/Gearman developer with Sun Microsystems. This was the position Brian Aker mentioned back in January.

Over nine years ago I was flying to the bay area for my job interview at Concentric. It’s been a great run and I’ve learned a tremendous amount there, writing everything from customized, multi-threaded HTTP and DNS servers to a clustered, hierarchical object database with a full query language. The environment at Concentric feels like a family, probably because a number of co-workers have been there even longer than me. It was a tough decision to make, and I …

I can’t stress enough that people look at SQL statements that are being executed against your production MySQL database, and you optimize queries when you can.

Often it’s the improvement to the large number of similar queries executed that can optimize resources. In this example, we take a very simple query, and by removing an unnecessary order by, we eliminate MySQL internally creating a temporary (in memory) table.

So what’s the big deal.

• The query is simpler to read and understand
• Memory required for the connection is not assigned
• A number of internal steps are no longer required (4 of 21 logging messages, not an ideal measurement, but an indication). In this case, it was easily a 10% performance improvement for each query.

This query is executed 10-100 times per second, so the improvement in performance is significant.
