I wanted to point out something that might not be obvious from the name: MySQL Parallel Dump can be used as a generic wrapper to discover tables and databases, and fork off worker processes to do something to them in parallel. That “something” can easily be invoking mysqlcheck – or any other program. This makes it really easy for you to do multi-threaded whatever-you-need-to-do on MySQL tables. Here’s how: mysql-parallel-dump [options] -- 'mysqlcheck --optimize %D %N' There are several things going on here:

Taking photos is easy. Processing them is hard. By processing I mean, going through them, ditching ones that didn’t quite make the cut, and then uploading them. Note processing does not even mean editing them in The Gimp.

The reception was amazing, heaps of people won gifts, and kudos again to the organisers. Drinking black vodka, aka Salmiakki that Monty brought, was definitely a treat for those who rocked up to the reception.

I wrote a couple weeks ago about my work on the Backup and Recovery chapter for High Performance MySQL, 2nd Edition. Thanks for your comments and suggestions, and thanks to those of you who helped me over email as well.

I've had several questions about what is included in the chapter, so I thought I'd post the outline as it stands now.

I’ve come in late for Monty’s session - everything seems to be running a bit early - how odd.

Monty’s is covering mistakes in building communities - he’s talking about Dream Box and how they have let their community fragment so deeply. Then he talks about how MySQL has provided a strong central point for the development of the server.

At this point someone asks how much contributed code is in MySQL. Monty says very little in the core server (but mentioning the Windows port as a large and notable exception). He should mention that the non-server contributions are huge, but he gets sidetracked.

He heads back to his slides and start discussion stats from MySQL’s past - how many copies have been distributed (and estimated 100 million+ - about 40k downloads per day.) Lots and lots of books (about 250 in English, 200 in German, 200 in French, 50 in Japanese and 20+ in Spanish. Also in Chinese, Russina, Portuguese, …

I did not attend the talk Monty gave at OpenMind 2007. I only have Zak's recollections to go by and among various interesting tidbits I found the following note by Zak: "DBMS implementations must change. FLOSS DBMS will be able to react most quickly to changes in what people want and what hardware offers. They can react quickly, because FLOSS DBMS focus on serving users first and worrying about standards, marketing and so on afterwards."

Now I actually agree on the point regarding standards .. well sort of. I guess that Zak simply had to leave out some context in his notes in order to not end up with a full length transcript. I assume the point that Monty was trying to make is that FLOSS has the advantage in adapting to change, because that change is happening in …
