Very Interesting Tool

I spent some time with a an IT expert who was praising Round Robin Database. It seems very cool. Can't wait until I have time to check it out. It stores data (like time series data) in such a way that over time the file doesn't grow but you lose resolution. It's very interesting, as whom really wants to know about router performance down the 5 minute interval two years from now, but you might want to know about performance for this month versus a year ago.
