> Near the end of StoreScanner.next(...) we find this gem:
> {code}
> } finally {
> if (cumulativeMetric > 0 && metric != null) {
> RegionMetricsStorage.incrNumericMetric(this.metricNamePrefix + metric,
> cumulativeMetric);
> }
> }
> {code}
> So, for each row generated we build up a new metric string, that will be
> identical for each invocation of the StoreScanner anyway (a store scanner is
> valid for at most one region and one operation).
