bq. Can you tell me the use case ? Listing all DAGs' or listing DAGs' within an
app ? Or something else ? Typically how many DAGs' can there be per app ?
Basic use case is to achieve pagination nevertheless apps/flows/entities such
as DAG or containers or any other user entities or system entities. Currently
limit is 100 for any entities to retrieve. Say if number of entities is 200.
Then REST call retrieves 100 entities. And how to retrieve 100 to 200 entities?

> TimelineReader REST API's provides lot of filters to retrieve the
> applications. Along with those, it would be good to add new filter i.e fromId
> so that entities can be retrieved after the fromId.
> Example : If applications are stored database, app-1 app-2 ... app-10.
> *getApps?limit=5* gives app-1 to app-10. But to retrieve next 5 apps, it is
> difficult.
> So proposal is to have fromId in the filter like
> *getApps?limit=5&&fromId=app-5* which gives list of apps from app-6 to
> app-10.
> This is very useful for pagination in web UI.
