Hi Moon, Thanks for your quick response.
1. For first question, got your answer. that means all meta info, paragraph, and result of one notebook will be cached in memory once loaded, right? 2. For #2, my real question will be how to serve millions of users for Zeppelin. Per my current understanding REST API and websocket connection handling will be coupled together within one server, if it’s true, then my original question will become to “how to scale out the server that servers REST API, Websocket connection”, or not, what’s the differences of scaling them when I wanna support more users?

So number of notebooks supported by instance will be limited by the memory on the system. Scale out Zeppelin-Server you mean scale out the server that serves REST API, Websocket connection?

Capacity limitation of Zeppelin-Server, in other words, how many notebook instance one server can support 2. If we want to scale out Zepplein-server, is that possible? If so, then how? Let’s say the environment it’s yarn + spark Regards, Dafeng
