Class AccumuloMetricStore

java.lang.Object

org.calrissian.accumulorecipes.metricsstore.impl.AccumuloMetricStore

All Implemented Interfaces:

MetricStore

Direct Known Subclasses:

AccumuloCustomMetricStore, AccumuloStatsMetricStore

public class AccumuloMetricStore
extends Object
implements MetricStore

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 SummingCombiner against each of the columns specified.
