(PPS. Going back to our chat about drill speed the other week, I'm not saying Drill is actually the most performant or best in terms of what people need, but in terms of a tool to connect to lots of stuff and offer pretty useful data federation, its top of my list. I do have Phoenix, Kylin etc sat on the backburner because the should offer more performance but for more specific usecases.)
