Class RetryPolicy

java.lang.Object

software.amazon.awssdk.core.retry.RetryPolicy

All Implemented Interfaces:

ToCopyableBuilder<RetryPolicy.Builder,RetryPolicy>

@Immutable
public final class RetryPolicy
extends Object
implements ToCopyableBuilder<RetryPolicy.Builder,RetryPolicy>

Interface for specifying a retry policy to use when evaluating whether or not a request should be retried. The builder()} can be used to construct a retry policy from SDK provided policies or policies that directly implement BackoffStrategy and/or RetryCondition. This is configured on a client via ClientOverrideConfiguration.Builder#retryPolicy. When using the builder() the SDK will use default values for fields that are not provided. The default number of retries and condition is based on the current RetryMode.

Method Detail

defaultRetryPolicy

public static RetryPolicy defaultRetryPolicy()

Create a RetryPolicy using the RetryMode.defaultRetryMode() defaults.

forRetryMode

public static RetryPolicy forRetryMode(RetryMode retryMode)

Create a RetryPolicy using the provided RetryMode defaults.

none

public static RetryPolicy none()

Create a RetryPolicy that will NEVER retry.

builder

public static RetryPolicy.Builder builder()

Create a RetryPolicy.Builder populated with the defaults from the RetryMode.defaultRetryMode().

builder

public static RetryPolicy.Builder builder(RetryMode retryMode)

Create a RetryPolicy.Builder populated with the defaults from the provided RetryMode.

retryMode

public RetryMode retryMode()

Retrieve the RetryMode that was used to determine the defaults for this retry policy.

isFastFailRateLimiting

public Boolean isFastFailRateLimiting()

When using RetryMode.ADAPTIVE retry mode, this controls the client should immediately fail the request when not enough capacity is immediately available from the rate limiter to execute the request, instead of waiting for capacity to be available.

additionalRetryConditionsAllowed

public boolean additionalRetryConditionsAllowed()

Returns true if service-specific conditions are allowed on this policy (e.g. more conditions may be added by the SDK if they are recommended).

aggregateRetryCondition

public RetryCondition aggregateRetryCondition()

Retrieve the retry condition that aggregates the RetryPolicy.Builder.retryCondition(RetryCondition), RetryPolicy.Builder.numRetries(Integer) and RetryPolicy.Builder.retryCapacityCondition(RetryCondition) configured on the builder.

retryCondition

public RetryCondition retryCondition()

Retrieve the RetryPolicy.Builder.retryCondition(RetryCondition) configured on the builder.

backoffStrategy

public BackoffStrategy backoffStrategy()

Retrieve the RetryPolicy.Builder.backoffStrategy(BackoffStrategy) configured on the builder.

throttlingBackoffStrategy

public BackoffStrategy throttlingBackoffStrategy()

Retrieve the RetryPolicy.Builder.throttlingBackoffStrategy(BackoffStrategy) configured on the builder.

numRetries

public Integer numRetries()

Retrieve the RetryPolicy.Builder.numRetries(Integer) configured on the builder.
