This would be useful in case of getEntity() API. So do we specify this time window separately for each metric to be retrieved or same for all metrics ? # Queries based on relations i.e. queries such as get all containers for an app. We can return relatesto 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 ? # Some understanding on how flow id, flow run id will be stored is required. > [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_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)
