-----------------------------------
Parent Issue: YARN-5355 (was: YARN-2928)
> Entity created time should be part of the row key of entity table
> -----------------------------------------------------------------
>
> Key: YARN-3914
> URL: https://issues.apache.org/jira/browse/YARN-3914
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: timelineserver
> Reporter: Zhijie Shen

> Entity created time should be part of the row key of entity table, between
> entity type and entity Id. The reason to have it is to index the entities.
> Though we cannot index the entities for all kinds of information, indexing
> them according to the created time is very necessary. Without it, every query
> for the latest entities that belong to an application and a type will scan
> through all the entities that belong to them. For example, if we want to list
> the 100 latest started containers in an YARN app.
