There is no integration for any db setup at the moment, but this is one of the next things we will tackle for sure! Druid was not on our radar, seems like it is used a lot in automotive/aerospace. Never tested superset, I'll give it a try. But it looks to be more like a dashboarding tool. Our goal is to provide an investigative tool that allows the user to detect problems and in a very interactive way change the visualisation.
