Class ExponentialDelayWithJitter

java.lang.Object

software.amazon.awssdk.retries.api.internal.backoff.ExponentialDelayWithJitter

All Implemented Interfaces:

BackoffStrategy

public final class ExponentialDelayWithJitter
extends Object
implements BackoffStrategy

Strategy that waits for a random period of time between 0ms and an exponentially increasing amount of time between each subsequent attempt of the same call.

Specifically, the first attempt waits 0ms, and each subsequent attempt waits between 0ms and min(maxDelay, baseDelay * (1 << (attempt - 2))).
