Introduction to Gearman at the Italian Research Council
+0 Vote Up -0Vote Down



I was invited to contribute some technological views at the Italian National Research Center, during the Internet Governance Forum.
My contribution was ahigh level introduction to Gearman, which sparked a debate about the impact of the cloud on the future of open source. Indeed, cloud computing technologies have the potential of harming open source adoption. If this is a threat and how much it can affect the future of open source depends on the business model behind the cloud.

More interesting topics were discussed both during the scheduled sessions and in open

Gearman Slides from San Francisco Meetup
+0 Vote Up -0Vote Down

Thanks to everyone who came out to the San Francisco PHP and MySQL meetup! Also, thanks to Michael for organizing such a great event, and Percona for sponsoring the food. I put the slides from the talk up on my wiki for reference or in case you missed it. I believe that there will be a video up at some point as well. While down there I also had a chance to stop by Digg and talked to them about Gearman (they’ve been using it for a while). It was interesting to see how they were using it in a large scale deployment. I was able to get some valuable feedback to future development, and a cool t-shirt. :) Thanks Digg!

Gearman at San Francisco PHP and MYSQL Meetup
+1 Vote Up -0Vote Down

I’ll be talking about Gearman this Thursday (October 1st, 2009) at the San Francisco PHP and MySQL Meetup groups (these are two separate groups, but sometimes share the topic). A few other folks involved in the Gearman community should also be there to help out, including James Luedke (the PHP extension main author), Eric Lambert (the Java API author), Dormando, and Hachi (Perl version maintainers at SixApart). You can sign up at either the MySQL or PHP meetup groups. We’ll be discussing the basics for those of you who don’t even know what Gearman is, common use cases, new features, advanced topics for folks already using Gearman, and of course Q&A throughout. Hope to see you there!

SQL Analysis with MySQL Proxy – Part 2
+2 Vote Up -0Vote Down

As I outlined in Part 1 MySQL Proxy can be one tool for performing SQL analysis. The impact with any monitoring is the art of monitoring will affect the results, in this case the performance. I don’t recommend enabling this level of detailed monitoring in production, these techniques are designed for development, testing, and possibly stress testing.

This leads to the question, how do I monitor SQL in production? The simple answer to this question is, Sampling. Take a representative sample of your production system. The implementation of this depends on many factors including your programming technology stack, and your MySQL topology.

If for example you are using PHP, then defining MySQL proxy on a production system, and executing firewall rules to

Drizzle and the Gearman logging plug-in

I have been meaning to look at Gearman for a long time, but I just couldn't find any project where I could use it.

Well, that was true until last week a couple of weeks ago, when I started to put together Drizzle, the Gearman logging plug-in, Perl and the Enterprise Monitor (http://www.mysql.com/products/enterprise/monitor.html).

As I was finishing writing the agent.pl script, I thought that it would be a good idea to split the script in at least two components: one that would just collect the queries, and another component that would do the processing of the log entries (replacing the

Drizzle query monitoring

A little over a month ago, Ronald posted a blog about the different query logging plug-ins that are available for Drizzle. This was pretty exciting news, especially when I saw the details that were included in the logs.

Meanwhile, a few weeks ago, I started looking at the REST API that comes with the MySQL Enterprise Monitor (http://www.mysql.com/products/enterprise/monitor.html).

The result is that we can now see most of the information returned by the plug-in, on the Dashboard.

Drizzle, Gearman, and memcached Meetings
+2 Vote Up -0Vote Down

As Brian mentioned, a number of us traveled up to Seattle last week to discuss the road map for Drizzle, Gearman, and memcached. Thanks to everyone who was able to make it! It was great to see folks again (Northscale guys, Robert Hodges, Padraig), and meet a couple new people like Nathan, one of the Google Summer of Code students for Drizzle. I thought I’d take a moment to mention some of the discussions related to the tasks I’m working on.

For Drizzle, we talked about the new configuration and plugin system I’ve been digging into lately. Monty Taylor has been doing a great job refactoring the plugin loading, but there are still some steps to be taken to get things where we want. One of the big goals with all this is to have the plugin and config system not specific to Drizzle at all so we can use this in other projects as well (one being

C vs C++
+3 Vote Up -0Vote Down

Linux vs FreeBSD, vi vs emacs, MySQL vs PostgreSQL, your habit or favorite technology vs another’s. At the end of the day there is no winner, just a matter of preference for the task at hand. I learned C++ 13 years ago, I forgot most of my C++ knowledge 10 years ago, I discouraged the use of C++ in this period in between, and in the past year I’ve been re-learning C++ (mostly due to Drizzle). So what did I use after unlearning C++ 10 years ago? I wrote everything in C (and by everything I mean this was my performance programming language of choice). This worked quite well, but it’s an interesting evolution that I think is now coming full circle.

When I first started programming C, it was a bit clumsy, and I look back at my old code and cringe. I began to develop a certain programming style that can best be described as object-oriented C programming due to the conventions used. The structs,
