A couple of years ago at our company, the idea came up to rank the most influential people in the social media space, per topic. Since the calculations for this are substantial and chew on a lot of data, I figured it should run in the database. “Oh yeah,” I said, “I’ll code that. How long could it take?” Famous last words.
It worked for a while running in the main database, but since then we have a lot more data and the “influencer” calculation has grown much more complex. Several months ago, due to the load this calculation placed on the main database, we moved it off to a dedicated set of servers. The work is done there and the results are sent back, and it’s been working quite well for months.
This system works because our application of it satisfies several requirements:
This presentation will begin by reviewing several key concepts that are the foundation of this system, including:
After the concept review, there’s a high-level overview of our distributed system:
Finally, we’ll look at the code involved. A generalized (but functional) version of the work-distribution code will be available for download following the presentation. Even if this system isn’t an exact match to your intense-computation problem, I’m confident that seeing what we did will lead you to your own solution.
Bob has been squeezing every drop out of MySQL for a couple of years (and becoming the 14th Canadian to get certified), having previously spent several years roaming in the Garden of Oracle. In late 2007, he found himself suddenly (and without warning) responsible for storing and retrieving all the information amassed at Radian6, the social media monitoring company.
