Class ExponentialBackoffRetryPolicy

java.lang.Object

outbox.dispatch.ExponentialBackoffRetryPolicy

All Implemented Interfaces:

RetryPolicy

public final class ExponentialBackoffRetryPolicy
extends Object
implements RetryPolicy

Retry policy using exponential backoff with jitter.

Delay formula: baseDelay * 2^(attempt-1), capped at maxDelay, with random jitter in the range [0.5, 1.5).
