Class WritePathLatencySensor

java.lang.Object

com.linkedin.davinci.stats.WritePathLatencySensor

public class WritePathLatencySensor
extends Object

This class serves as a latency sensor for write path that contains two types of stats: Avg and Max. Note that this latency sensor should only be used in to write path as read path latency evaluation will need more information than just max and average, e.g. 50/99 percentile numbers.
