Class AccumuloStatsMetricStore

java.lang.Object

org.calrissian.accumulorecipes.metricsstore.impl.AccumuloMetricStore

org.calrissian.accumulorecipes.metricsstore.ext.stats.impl.AccumuloStatsMetricStore

All Implemented Interfaces:

StatsMetricStore, MetricStore

public class AccumuloStatsMetricStore
extends AccumuloMetricStore
implements StatsMetricStore

This class will store simple metric data into accumulo. The metrics will aggregate over predefined time intervals but are available immediately to query. Format of the table: Rowid CF CQ Value grouprevTS 'MINUTES' typename value grouprevTS 'HOURS' typename value grouprevTS 'DAYS' typename value grouprevTS 'MONTHS' typename value The table is configured to use a StatsCombiner against each of the columns specified.
