also is ssd recommended only for pinot server or for everything .. also if we are not loading offline segments .. do we really need 3 pods of minion .. and if ram is 8gb * 3 = 24 gb for pinot server.. for broker, controller , minion . .what should be the ram allotment .. same goes for cpu cores if cores for server is 2.5 cores per pod * 3 = 7.5 cores .. how much core allotment will be prudent for controller , broker ,minion

Controller only needs storage to store the pushed segments. Deepstore is recommended for this, not local storage. broker does not need any local storage either

what about minion

Minion as well. CPU/Mem depends on the workload you want to throw at the cluster

is the workload real time data ingested or offline data loaded .. I mean minion is involved in real time ingestion also or only while loading data into offline tables
