Varun Saxena commented on YARN-5585: ------------------------------------ Hmm...Then what we can do is that fetch the specific entity mentioned in fromId using a HBase Get and get created time field for that entity ID. And then create a Scan with a Single Column Value filter to fetch entities with created time less than this entity. This however would still lead to all the entities within the scope of entity type being iterated over. However, the result set returned to client will be relatively smaller due to created time based single column value filter. Let me think more over it and see if there could be a better solution. > [Atsv2] Add a new filter fromId in REST endpoints > ------------------------------------------------- > > Key: YARN-5585 > URL: https://issues.apache.org/jira/browse/YARN-5585 > Project: Hadoop YARN > Issue Type: Sub-task > Components: timelinereader > Reporter: Rohith Sharma K S > Assignee: Rohith Sharma K S > Attachments: YARN-5585.v0.patch > > > 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. > Example : If applications are stored database, app-1 app-2 ... app-10. > *getApps?limit=5* gives app-1 to app-10. But to retrieve next 5 apps, it is > difficult. > 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. > This is very useful for pagination in web UI. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
