Last week I delivered a talk titled "MySQL and Search at Craigslist" as part of the 2009 MySQL Conference and Expo. I talked about some of the good and bad of our MySQL work and also talked a lot about our recent Sphinx deployment. The slides are embedded below and here, thanks to SlideShare. (Anyone know why Google Docs doesn't yet handle OpenOffice presentations?)

[Read more]There have been ongoing rumors about a license change of the MySQL documentation. Karen Tegan Padir even asked the audience during her keynote at the MySQL Conference last week. Some liked it, but we didn't experience any overwhelming positive feedback. Currently, the MySQL Reference Manual and other MySQL documentation are released under regular copyright. Note, however, that Sun grants permission to use the docs in many ways that don't require written approval.
Most people in open source land believe that if the software is free then also the documentation should be (this is, for example, stated by the Free Software Foundation, in the preamble of the GNU Free Documentation License).
I agree with that …
[Read more]Just to clarify, this is a comparison of Calpont performance against the BKA performance. Calpont uses a multi-threaded, distributed hash join operation rather than an index operation, and so does not use the BKA access directly. Note that the BKA performance enhancement clearly is the right direction to improve index operations. This comparison just shows the power of hash join for big data.
Result graphed. Note that the graphic contains multiple comparisons with differing conditions.
The first 2 metrics come from the 2008 UC presentation, the third a Calpont run at a scale factor of 1 (6 million rows in lineitem table), and are disk runs. Calpont is configured with one performance module.
The next 2 metrics scale the number of rows by 10x, and 100x with Calpont timings, again disk timings, and again 1 performance module.
The next metric used sf100 (600 million rows in …

One of my favorite projects in the MySQL community is, of course,
Drizzle. In
fact, if I had to rank these sorts of things, I would say
PBXT is my
favorite project, with Drizzle being a very close second. There's
plenty of reasons why, but the biggest thing that attracts me is
that Drizzle can be anything to everyone. It often gets branded
as a Cloud DB, and while Cloud is a big piece, it's really
side-stepping the whole point. What makes it so enticing in the
Cloud is what makes it enticing for everyone else too.
Namely that they took MySQL, threw out all the bad, scrapped off
all the cruft, and ended up with a beautiful, small, simple
database platform. That, in it is itself, doesn't do it for me.
Granted, they removed some ugly features of MySQL such as
sql_mode and are moving towards transactional engines being the
default …
Background Knowledge
I’m running PHP v5.2.9-2 with SQL Server 2005 Express on Windows Server 2003 R2 SP2.
Error Message
Warning: mssql_query() [function.mssql-query]: message: Unicode data in a Unicode-only collation or ntext data cannot be sent to clients using DB-Library (such as ISQL) or ODBC version 3.7 or earlier. (severity 16)
Solution
Specify the database columns within your database query (select filed1, field2 from foo). Avoid doing queries with the wildcard (*), select * from foo.

Attending the MySQL Users Conference in 2006, I had one of the best days of my career. At the morning keynote, my name was called, and I found myself on stage, together with Markus Popp, Roland Bouman, and Rasmus Lerdorf, being awarded a Community Member of the year crystal ball. That day is permanently in my mind as a very fond memory.
For this reason, it is a particular pleasure for me to be in a position to suggest the next ones who will hold the community awards. It is a collegial decision, not my own. Each member of the community team submits a few names, we discuss the pros and the cons, and then we settle for the first three names in the list.
This year, the agreement fell on three names, who were included for different reasons.

I have uploaded the presentations to the MySQL User Conference
website where it says these will be made available, once I
have done just that, uploaded them. That didn't seem to happen,
at least it seems to take some time, so I decided to do what
Guiseppe Maxia did, try out SlideShare, which
seems to work just great. Cool!
So my presentations from the MySQL User Conference 2009 are
available here:

When I joined MySQL in 2006, after several profitable years as a consultant, I had a dream. I wanted to improve the product that had contributed to my professional success. The first thing that I learned when I started the uphill task is that it was far more difficult than expected. MySQL called itself open source, but the development practices were for all practical purposes closed source. At the same time, I found that MySQL, below the surface, is an organization with complex and well oiled engineering practices. Indeed, opening up the cathedral, as Lenz put it, was a hard nut to crack. We had a closed source revision control system, and our developers loved it so much, that any proposal to change it was met with strong opposition. We discussed technical matters behind the firewall. Our … |
This Thursday (April 30th, 14:00 UTC), Giuseppe
Maxia will give a MySQL University session on Testing Multiple Servers With MySQL Sandbox.
Giuseppe is the creator of MySQL Sandbox, and has recently
announced a new Sandbox version and other
interesting changes, for example the --query-analyzer option to make_sandbox
(but note the date when this was announced!).
