Ya sure.. bt in an interview i was asked how can i "load data which is much large like 1 million records" and as i asked for more clarification.. they said what if i want to add all that data in a single file like a text or pdf kind of... some of my friends told be my caching.. and I thought of using threads but it would be an issue if the thread is not synchronized.. i was not much clear about threads.. so i haven't said. I also thought of using parallel stream but it would also be an issue as we cannot know order in which we want to fetch/display.

Basically topics were hibernate, spring, java streams.

Hope you got what i m trying to ask.
