Class AccumuloCustomMetricStore

java.lang.Object

org.calrissian.accumulorecipes.metricsstore.impl.AccumuloMetricStore

org.calrissian.accumulorecipes.metricsstore.ext.custom.impl.AccumuloCustomMetricStore

All Implemented Interfaces:

CustomMetricStore, MetricStore

public class AccumuloCustomMetricStore
extends AccumuloMetricStore
implements CustomMetricStore

This implementation of the metric service allows the caller to specify a custom function during query time. No table configured iterators are setup for this table, as this might skew the results for any custom function. This means that during a compaction, the table is not able to consolidate data possibly increasing the query times for metric data. Format of the table: Rowid CF CQ Value grouprevTS 'MINUTES' typename value grouprevTS 'HOURS' typename value grouprevTS 'DAYS' typename value grouprevTS 'MONTHS' typename value
