Varun Saxena commented on YARN-5626:
------------------------------------
This is actually about passing different flow context information in
TimelineEntity itself (despite these entities being published from the same
app).
But we need to then consider if we need to distribute the workload and let more
than one collector handle an app.
> Support long running apps handling multiple flows

> Many applications which can potentially use ATS have one or a few long
> running AMs' which handle multiple tasks or serve multiple queries. As ATS
> scopes everything within an app, its not possible for us to differentiate
> different flows.
> Moreover, all entities will be written to one or very few node collectors as
> writers are distributed based on app
