ExponentialDelayWithHalfJitter (AWS Java SDK :: Retries API 2.33.0 API)

java.lang.Object
- software.amazon.awssdk.retries.api.internal.backoff.ExponentialDelayWithHalfJitter

All Implemented Interfaces:

BackoffStrategy
```
public final class ExponentialDelayWithHalfJitter
extends Object
implements BackoffStrategy
```
Strategy that waits for a random period of time between a lower bound x and an exponentially increasing amount of time between each subsequent attempt of the same call. The lower bound x is half the amount of the computed exponential delay.
Specifically, the first attempt waits 0ms, and each subsequent attempt waits between min(maxDelay, baseDelay * (1 << (attempt - 2))) / 2 and min(maxDelay, baseDelay * (1 << (attempt - 2))).
This is in contrast to ExponentialDelayWithJitter where the final computed delay before the next retry will be between 0 and the computed exponential delay.
