> The aim of this JIRA is to develop distributed counters framework in REEF. Each task can emit pairs of {counter name, incremental value} which are aggregated and sent to driver, which can then aggregate them from all the tasks/ evaluators. The aggregation strategy can be simple addition, most recently used, etc.  Via these counters, we can implement some common metrics for ML - like amount (bytes) of data read, current loss function value etc.
> We will develop interfaces for Counters for evaluators and driver along with default implementations and aggregation strategies.
