Varun Saxena commented on YARN-3051:

Some use case scenarios which are pending.
# To plot graphs based on timeseries data, we may need to provide a time window 
for metrics too. This would be useful in case of getEntity() API. So do we 
specify this time window separately for each metric to be retrieved or same for 
all metrics ?
# Queries based on relations i.e. queries such as get all containers for an 
app. We can return relatesto field while querying for an app. And then client 
can use this result to fetch detailed info about related entities. Is that fine 
? Or we have to be handle it as part of a single query ? 
# Some understanding on how flow id, flow run id will be stored is required.
