> Each task can collect various metrics, like input data volume, output data volume, shuffle data volume, and so on. In this issue, I'll add Task metrics and improve QM to collect Task metrics and keep aggregated values of all task metrics. Then, I'll improve TajoMaster to keep the final aggregated metrics for each query.
