Class BlockWorkerMetrics

java.lang.Object

alluxio.worker.block.BlockWorkerMetrics

public class BlockWorkerMetrics
extends Object

The BlockMetaMetricCache cache the metric data of the BlockMeta from the BlockWorker. So the BlockWorker can pass this MetricCache to registerGauge instead of let registerGauge copy a whole BlockMeta everytime updating the metrics.
