And if I sound annoyed when talking about TokuDB performance, I am a bit. I wish someone else documented the performance problems it has. The problems are known but not much has been shared to explain them. That has been left to me as I am promoting the other write-optimized storage engine for MySQL. A lot of extremely talented people worked on TokuDB. A few (hello Rich) continue to help with it. One of them is related to me (hello Tim). One of them works for my employer (Zardosht). I wish more of them worked for my employer (anon, anon, anon). Now I get to be the jerk.
