java.lang.Object

org.calrissian.accumulorecipes.featurestore.ext.metrics.impl.AccumuloMetricsStore

All Implemented Interfaces:

MetricStore

public class AccumuloMetricsStore
extends Object
implements MetricStore

The Accumulo implementation of the metrics store allows the statistical summaries to be aggregated during the compaction and scan phases. Metrics gets automatically rolled up for the given time units.
