             Summary: Provide new timeline plugin storage to support fine-grained entity caching
                 Key: YARN-4265
                 URL: https://issues.apache.org/jira/browse/YARN-4265
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Li Lu
            Assignee: Li Lu


To support the newly proposed APIs in YARN-4234, we need to create a new plugin timeline store. The store may have similar behavior as the EntityFileTimelineStore proposed in YARN-3942, but cache date in cache id granularity, instead of application id granularity. Let's have this storage as a standalone one, instead of updating EntityFileTimelineStore, to keep the existing store (EntityFileTimelineStore) stable.
