Stu Hood, one of Mailtrust's software engineers wrote about MapReduce at Rackspace back in January, detailing how they use Hadoop for processing "several hundred gigabytes of email log data" every day. We have his presentation here for your viewing:

Can you provide a download link to this video? I tried to hit pause like in Youtube and it didn't load the video in the buffer. The video to me is choppy and stops every five seconds.

It seems that the talk is really interesting but I'm having problems watching the streaming video. Is there way to download it?

We aren't able to provide a download option for certain videos. Unfortunately, this is one in that category, so the online streaming is the only option.

Brian, could you downgrade the video? I clicked on the share button and went to the website. I saw that this video is being streamed at 700kbps. There isn't a 128k - 256k version?

I found the video on Yahoo! Video - http://video.yahoo.com/watch/2241669/7074711. I loaded only the beginning and hit pause. It is loading the entire video and I will watch it later.

Nice talk, but:
1. SQL is a language, not a system or class of systems
2. database systems do scan,sort,merge access patterns in much the same way as map-reduce; the distinction between database systems and map-reduce is much more subtle than that index vs. scan.

It seems this video can't be watched outside Yahoo!?
Any chance of changing that?
Thanks.
