> The basic skeleton of the timeline aggregator has been set up by YARN-3030. We need to implement the core functionality of the base aggregator service. The key things include
> - handling the requests from clients (sync or async)
> - buffering data
> - handling the aggregation logic
> - invoking the storage API
