Varun Saxena commented on YARN-5585:
------------------------------------
bq. Just realized that a normal converter will not address the use case where
users really want entities sorted by their creation time
Yes, this is just for use cases where entity IDs' are structured in a manner
where there is direct correlation between entity ID and being sorted by
creation time. DAG ID seems to be generated same way. And seems to be the case
in Spark too. If row keys are sorted that will be the best solution from a
performance perspective. However, there is that disadvantage of putting the
burden of it on the application to write some extra code and make sure that
JARs' are placed during deployment. That is why I asked if this will be
acceptable to Tez.
On further thought though, we can also break ATS related behavior for the
application if they do choose to change their IDs' in a manner where its no
longer sorted in future, however unlikely that may be.
Let me think of something else then.

> 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.
