MySQL has deep roots in open-source software development communities and code contributions to MySQL keep flowing in, being reviewed and integrated into the MySQL. 

During our BoF at the MySQL Conference and Expo, Lenz Grimmer talked about our work to make MySQL (even more) contributor friendly, with some more focused effort starting on February 1, 20091.

The desire to contribute code to MySQL remains as strong as ever as evidenced by this year's MySQL Conference and Expo, where I had an opportunity to speak with some contributors and partners who wish to contribute to MySQL. Of course, there are a lot of strong and varying opinions in this area.

After getting the http://jan.kneschke.de/2009/4/22/druckbetankung stuff working and discussing the idea with the replication team we figured out that my presented approach has a nice hack-value, but otherwise is perhaps a bit too complicated. The same result can be achieved by a more simplified approach:

• turn our input data into a RBR based base64-encoded BINLOG-stmt using binlog
• use the mysql client to push the data into the server

The BINLOG stmt is used by mysqlbinlog to pass the RBR-events through the mysql client to the mysql-server. Usually it wraps a FORMAT_DESCRIPTION_EVENT and the TABLE_MAP_EVENT and the *_ROWS_EVENTS. BUT … it can handle any binlog-event. Just try

I went looking for the MySQL 5.4 documentation today, but alas I could not find it. In particular, I went looking for the list of changes between 5.1.34 and 5.4.1.

If 5.4.1 is beta then it should definitely have documentation, at least in beta form. This is especially true in light of the Sun MySQL conference keynote kind of dangling a carrot on a stick, as it were, with a question to the audience about opening the docs up under the GPL. The comments system also needs updated too. I think that if public comments are available on the web site, then those comments should have a rating system attached so that crappy, wrong and useless manual comments can easily be filtered. But I digress.

So, Sun, when are going to release all the MySQL documents under the GPL? Is it going to be in the MySQL 5.4 time frame, or in some far off hazy future? And why are there no 5.4 documents available online, when the binaries are already …

Last week at the Drizzle developer day a few people were surprised at the number of plugin interfaces we’ve created already. I created this image to give a sampling of interfaces and plugins:

As you can see, things are quite different from MySQL.

Having read a weeks worth of reactions to MySQL ending up at Oracle, I just want to say that by far the aptest1 commentary goes to Chris Powers from the Falcon team. A picture indeed says more than 1k words:

Now I know it is not the apocalypse and we probably won't be crucified either. But I do sympathise with the Falcon team, their reason of existence certainly is put more into question than us in general.

The prize to the most astonishing prediction goes to John …

Following on from the announcement  at the User Conference last week that MySQL Cluster 7.0 is now generally available, Mat Keep and I will present the first public webcast this Thursday. If you’d like to attend but the time isn’t convenient then you can either watch/listen to the recording after the event or wait for the next one to be announced (will be aimed at different time-zones).

What’s New in the Next Generation of MySQL Cluster?
Thursday, April 30, 2009

Whether you’re racing to introduce a new service, or trying to manage an avalanche of data in real time, your database has to be scalable, fast and highly available to meet ever-changing market conditions and stringent SLAs.

By attending this webinar, you will learn more about MySQL Cluster 7, and how it enables you to deliver 99.999% database availability, with real time performance and linear scalability, while slashing …

George Trujillo at Collaborate 09 Week of May 3, 2009 I will be presenting two presentations at the IOUG Collaborate 09 Conference in Orlando FL, the week of May 3rd 2009. Here is one I have been asked to present. This presentation is a very detailed technical presentation designed for experienced Oracle professionals to get an understanding of the MySQL database server under the hood.
