A project I have been working on for a while just hit a
significant milestone.
Pluggable Query Logging has just been merged into the main
Drizzle development.
The plan is that quickly this will replace the existing query log
and slow query log that Drizzle inherited from MySQL.
The legacy logging system is more than a bit byzantine, is full
of a lot of complexity to try to get incremental performance with
complicated buffering, and yet has several completely unnecessary
locks.
In the new plugin logging system, there is a callback right after
a query is parsed but before it is executed, and another one
right after it is done executing. A plugin registers itself, and
will be called at those two points, and is passed the THD, from
which it can learn everything about the query that will be / has
been executed, and then do whatever it …
Bom dia!
On Monday and Tuesday this week, a team of MySQLers (”Sun Dolphins”) and Sunnies (”Sun Classics”) launched the commercial presence of MySQL in Brazil.
This means we have now have ambitions well beyond the growth of the MySQL user base in Brazil, which already is in the top five countries of the world when it comes to downloads. In other words,
- we have a senior sales person assigned, with a sales goal for Brazil
- we are recruiting sales engineers for Brazil
- we are recruiting Support Engineers, who will deliver MySQL support in Portuguese
- we are recruiting Consultants, who will deliver MySQL professional services in Portuguese
During the Sun Tech Days in São Paulo, we …

I spoke at the MySQL Conference and Expo this year about the
architecture we have here at dealnews.com. After my talk, Jimmy Guerrero
of Sun/MySQL invited me to give a webinar on how dealnews uses
memcached. That is taking place next week, Thursday,
October 09, 2008. It is a free webinar. We have used
memcached in a variety of ways as we have grown. So, I will be
talking about how dealnews used memcached in the past and
present.

I've been doing an informal poll recently of open-source companies, asking them how the tight economy is affecting their sales. In every single case, these companies are recording record sales.
It's perhaps not hard to find an answer: open-source solutions tend to cost a lot less than their proprietary counterparts, and provide equal or better functionality.
Open source is not merely about lower software price tags, however. As CIO.com highlights with the Oregon Department of Human Services' attempt to find a new CRM system, the cost of product discovery and implementation also favor open source, in this case SugarCRM: …
[Read more]Welcome to the 117th edition of Log Buffer, the weekly review of database blogs.
For those of you who don’t know me, my name is Nicklas Westerlund, and I’m a MySQL DBA with The Pythian Group. This is my first time writing Log Buffer, and I hope I’ll do it right.
Let’s start off with SQL Server, where Simon Sabin asks if you know what concurrency is and how to improve it. And on SatisticsIO, Jason Massie focuses on the …

It is the start of the last quarter of 2008 and we engineers in ISV Engineering are still baffled when we hear from new Startups when they say "Oh we are startups, I don't think we can afford Sun Microsystems" or sometimes even from old partners. It's like Flashback to 1999! Yes we were selling $4million servers based only on SPARC in 1999. However in 2008 we are selling many servers for much less than $1000. (HINT: Join Sun Startup Essentials) In fact now we sell systems based on various CPU architectures like AMD Opteron, Intel Xeon, UltraSPARC T2, SPARC64 VII. We also have one of the biggest OpenSource offerings right from MySQL, Java, …
