Queries based on relations i.e. queries such as get all containers for an app. We can return relates to field while querying for an app. And then client can use this result to fetch detailed info about related entities. Is that fine ? Or we have to be handle it as part of a single query ? >From our experience with ATS V1, these queries are critical for driving UIs of individual apps. Unlike before, we can definitely say that queries against relations can be restricted to one level of hierarchy and guide the app developers to model UIs that way. > [Storage abstraction] Create backing storage read interface for ATS readers > --------------------------------------------------------------------------- > > Key: YARN-3051 > URL: https://issues.apache.org/jira/browse/YARN-3051 > Project: Hadoop YARN > Issue Type: Sub-task > Components: timelineserver > Reporter: Sangjin Lee > Assignee: Varun Saxena > Attachments: YARN-3051.wip.patch, YARN-3051_temp.patch > > > Per design in YARN-2928, create backing storage read interface that can be implemented by multiple backing storage implementations. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
