Hi team, Regarding Pinot Cluster Design, 1) keeping controller along with Server is good approach? (w.r.t disk, memory and network). 2) If not, how to go about hosting controller? can we keep it along with any of the component? or it should be hosted alone? 3) If we keep controller separately, Won't a increase in hop will impact read and write performance?

please keep controllers separate, they can be very small footprint but better to keep them isolated from other components. It will save you from operational nightmares. read and writes do not go through controllers.

okay. Thanks @Kishore G
