Slashdot Mirror

An anonymous reader writes "Brian Aker, one of the core developers of MySQL, has written up a lengthy blog on how the Drizzle fork is handling both its code contributions and its testing. He has listed the tools they use and how they work with their processes. He also makes an interesting statement about the signing of corporate code-contribution agreements and how there are some, including Rasmus (creator of PHP), who refuse to sign them."

Brian Aker is Director of Architecture for MySQL AB. He has also worked on the code (and database) that runs Slashdot, and is well-known in both Apache and Perl circles. Outside of the arcane world of open source "back-end" programming, though, hardly anyone has heard of him. This is your chance to ask Brian (hopefully after looking at his blog and Wikipedia listing) about anything you like, from Perl to database architecture to open source philosophy to upcoming events in Seattle. We'll send Brian 10 of the highest-moderated questions approximately 24 hours after this post appears. His (verbatim) answers will appear late this week or early next week.

SlashRating^© 11.9 slashdottit! ^tm krow writes "One of the unique qualities of the MySQL server is its ability to have multiple storage engine operate concurrently. Companies like Oracle and Solid have contributed their own storage engines to the open source project. With 5.1 MySQL has added the ability to now do this in a loadable fashion, allowing dynamic engines in the same manner as Apache with its modules. Now PostgreSQL can add its self to the list of databases who have contributed a storage engine to MySQL. I'm releasing today a plugin so that you can now plugin the Postgres database engine into MySQL and have it work natively along side other engines."

A short time ago, Oracle announced its acquisition of Innobase, the Finnish company that makes the GPL'd InnoDB table storage engine. Among MySQL users, the separately-written InnoDB is almost as popular as the native MyISAM engine, and is considered to be more advanced for most purposes. Slashdot has, except for search, run entirely on InnoDB for the past year or two so we're as concerned about this as anybody. Brian Aker, former Slashdot coder and current Director of Architecture for MySQL AB, comments: "InnoDB is GPL, so once again the beauty of the open source market is at play: there is no lock in, and we can continue to develop Innodb as we see fit. The code is out there and we plan on continuing to support it. The largest database vendor in the world just confirmed that the market for open source databases exists."

Brian "Krow" Aker (Former Slashdot Coder now MySQL Employee) writes "I am pleased to announce the release candidate for MySQL 5.0. This version has been in development now for three years. We have worked to add update-able views, ansi stored procedures, and triggers. In addition we have added a number of fun features that we are experimenting with and resolved issues with bad data inserts (which personally annoyed the hell out of me when we rewrote Slashdot a couple of years back so I am happy to see this issue go away). We look forward to feedback on the candidate and will show some love for bug reports."

Java Coward writes "Eric Herman and MySQL's Brian "Krow" Aker have released code to allow the DBMS MySQL to run Java natively inside of the database. The code allows users to write functions inside of the database that can be then used in SELECT/INSERT/UPDATE statements. So when will someone do Ruby?"

ExcerLee asks: "Our team is going to build a MySQL (load-balancing and fail-over) cluster for the Cluster World Expo in the end of June. This cluster is going to have at least 10 nodes, and will use dual-opteron systems from Polywell Computers and SuSE Enterprise Linux for AMD64 from SuSE. While we are working on this hefty cluster, we wonder if this is the biggest MySQL cluster has ever been built. I googled with terms like 'biggest mysql cluster', but didn't find much." If you've run a MySQL cluster before, how large was it and how well did it perform? Krow: I have been told of much larger clusters then this; Slashdot DBs total 6 machines with 18 processors, and LiveJournal has one of the most complicated clusters I have ever seen set up.
