@Kishore G Hi Kishore Recent days,I try to install pinot cluster according to the online document. But I have some questions in my installation process. First, I don't understand the role of kafka component role in whole pinot cluster. Second, when I try to StartServer paramenter to start pinot server, how do I know if the server is realtime or offline? Could you give me some guide, thank you.

A server isn't realtime or offline, its the segments that are either realtime or offline

I see. Thank you for your reply.

Kafka is optional, thats only if you want to use realtime segments

+1 to what @vmarchaud said.

Can tableConfigFile parameter read remote config file? @vmarchaud

no

@Kishore G if only read local config file or data file, so there is a lot of pressure on my controller server such as disk space.

datafile can be remote

how to set the remote data file uri?
