All Implemented Interfaces:

BackoffStrategy, ToCopyableBuilder<FullJitterBackoffStrategy.Builder,FullJitterBackoffStrategy>

public final class FullJitterBackoffStrategy
extends Object
implements BackoffStrategy, ToCopyableBuilder<FullJitterBackoffStrategy.Builder,FullJitterBackoffStrategy>

Backoff strategy that uses a full jitter strategy for computing the next backoff delay. A full jitter strategy will always compute a new random delay between 0 and the computed exponential backoff for each subsequent request. For example, using a base delay of 100, a max backoff time of 10000 an exponential delay of 400 is computed for a second retry attempt. The final computed delay before the next retry will then be in the range of 0 to 400. This is in contrast to EqualJitterBackoffStrategy that computes a new random delay where the final computed delay before the next retry will be at least half of the computed exponential delay.

Method Detail

computeDelayBeforeNextRetry

public Duration computeDelayBeforeNextRetry(RetryPolicyContext context)

Description copied from interface: BackoffStrategy

Compute the delay before the next retry request. This strategy is only consulted when there will be a next retry.

Specified by:

computeDelayBeforeNextRetry in interface BackoffStrategy

Parameters:

context - Context about the state of the last request and information about the number of requests made.

Returns:

Amount of time in milliseconds to wait before the next attempt. Must be non-negative (can be zero).
