Class SamzaTransformMetricRegistry

java.lang.Object

org.apache.beam.runners.samza.metrics.SamzaTransformMetricRegistry

All Implemented Interfaces:

java.io.Serializable

public class SamzaTransformMetricRegistry
extends java.lang.Object
implements java.io.Serializable

SamzaTransformMetricRegistry is a registry that maintains the metrics for each transform. It maintains the average arrival time for each PCollection for a primitive transform.

For a non-data shuffling primitive transform, the average arrival time is calculated per watermark, per PCollection PValue and updated in avgArrivalTimeMap
