> We need application level aggregation of Timeline data:
> - To present end user aggregated states for each application, include: resource (CPU, Memory) consumption across all containers, number of containers launched/completed/failed, etc. We need this for apps while they are running as well as when they are done.
> - Also, framework specific metrics, e.g. HDFS_BYTES_READ, should be aggregated to show details of states in framework level.
> - Other level (Flow/User/Queue) aggregation can be more efficient to be based on Application-level aggregations rather than raw entity-level data as much less raws need to scan (with filter out non-aggregated entities, like: events, configurations, etc.).
