com.netflix.hystrix.metric.consumer.RollingCollapserBatchSizeDistributionStream

public class RollingCollapserBatchSizeDistributionStream
extends RollingDistributionStream<HystrixCollapserEvent>

Maintains a stream of batch size distributions for a given Command. There is a rolling window abstraction on this stream. The latency distribution object is calculated over a window of t1 milliseconds. This window has b buckets. Therefore, a new set of counters is produced every t2 (=t1/b) milliseconds t1 = HystrixCollapserProperties.metricsRollingPercentileWindowInMilliseconds() b = HystrixCollapserProperties.metricsRollingPercentileBucketSize() These values are stable - there's no peeking into a bucket until it is emitted These values get produced and cached in this class, as soon as this stream is queried for the first time.
