类 HistogramImpl

java.lang.Object

org.apache.hadoop.hbase.metrics.impl.HistogramImpl

所有已实现的接口:

Histogram, Metric

@InterfaceAudience.Private
public class HistogramImpl
extends Object
implements Histogram

Custom histogram implementation based on FastLongHistogram. Dropwizard-based histograms are slow compared to this implementation, so we are using our implementation here. See HBASE-15222.
