I definitely remember a lot of time spent tweaking histogram buckets for performance vs. accuracy. The default bucketing algorithm at the time was powers of 4 or something very unusual like that.
- shadowgovt 4y agoIt's because powers of four was great for the original application of statistics on high traffic services where the primary thing the user was interested in was deviations from the norm, and with a high traffic system the signal for what the norm is would be very strong. I tried applying it to a service with much lower traffic and found the bucketing to be extremely fussy.
