> 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.
> Current Behavior : Default limit is set to 100. If there are 1000 entities
> then REST call gives first/last 100 entities. How to retrieve next set of 100
> entities i.e 101 to 200 OR 900 to 801?
> Example : If applications are stored database, app-1 app-2 ... app-10.
> *getApps?limit=5* gives app-1 to app-5. But to retrieve next 5 apps, there is
> no way to achieve this.
> 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.
> Since ATS is targeting large number of entities storage, it is very common
> use case to get next set of entities using fromId rather than querying all
> the entites. This is very useful for pagination in web UI.
