Cool, I see mfiguiere linked to my recent blog post! Let me share a few words about it...

I took part in the One Billion Row challenge (1BRC). It was a lot of fun, but also a great learning experience. People came up with some pretty incredible optimization tricks. When you put them all together, it's a huge number, and they are all mingled up in individual solutions. They also happen on many levels -- from quite high, to incredibly low and detailed.

In retrospect, I could see there was a good number of tricks that are relatively easy to grasp, and reusable in other projects. I felt the urge to do a writeup that captures this knowledge in one place, isolating and explaining each of the tricks.

Thank you for taking the time to write it up. Really nice to see some modern Java, as well as the ideas with comments - many of which seem to generalize quite well - beyond Java and the jvm.

If you do find the time, I'm sure that writeup would be very valuable!
