Srimanth Gunturi commented on YARN-1838:
----------------------------------------
The _fromTs_ is needed because ATS can get events out of order. Without this
parameter, a query with _fromId_ will return varying results depending on when
you call it. The _fromTs_ prevents changes to the returned list so that it is
consistent.
> Timeline service getEntities API should provide ability to get entities from
> given id

>
> To support pagination, we need ability to get entities from a certain ID by
> providing a new param called {{fromid}}.
> For example on a page of 10 jobs, our first call will be like
> [http://server:8188/ws/v1/timeline/HIVE_QUERY_ID?fields=events,primaryfilters,otherinfo&limit=11]
> When user hits next, we would like to call
> [http://server:8188/ws/v1/timeline/HIVE_QUERY_ID?fields=events,primaryfilters,otherinfo&fromid=JID11&limit=11]
> and continue on for further _Next_ clicks
> On hitting back, we will make similar calls for previous items
> [http://server:8188/ws/v1/timeline/HIVE_QUERY_ID?fields=events,primaryfilters,otherinfo&fromid=JID1&limit=11]
> {{fromid}} should be inclusive of the id given.
