  • NO_RETRY_POLICY

    public static final RetryPolicy NO_RETRY_POLICY

    No retry policy

  • DEFAULT_MAX_ERROR_RETRY

    public static final int DEFAULT_MAX_ERROR_RETRY

    SDK default max retry count for legacy retry mode

    See Also:

    Constant Field Values

  • DEFAULT_MAX_ERROR_RETRY_STANDARD_MODE

    public static final int DEFAULT_MAX_ERROR_RETRY_STANDARD_MODE

    SDK default max retry count for standard retry mode

    See Also:

    Constant Field Values

  • DEFAULT

    public static final RetryPolicy DEFAULT

    SDK default retry policy. Amazon DynamoDB has a custom retry policy that is used when no ClientConfiguration is provided.

  • DYNAMODB_DEFAULT_MAX_ERROR_RETRY

    public static final int DYNAMODB_DEFAULT_MAX_ERROR_RETRY

    Standard max retry count for DynamoDB client for DynamoDB client

    See Also:

    Constant Field Values

  • DYNAMODB_DEFAULT

    public static final RetryPolicy DYNAMODB_DEFAULT

    Default policy for DynamoDB client

  • DEFAULT_RETRY_CONDITION

    public static final RetryPolicy.RetryCondition DEFAULT_RETRY_CONDITION

    The SDK default retry condition, which checks for various conditions in the following order:

    • Never retry on requests with non-repeatable content;
    • Retry on client exceptions caused by IOException;
    • Retry on service exceptions that are either 500 internal server errors, 503 service unavailable errors, service throttling errors or clock skew errors.

  • DEFAULT_BACKOFF_STRATEGY

    public static final RetryPolicy.BackoffStrategy DEFAULT_BACKOFF_STRATEGY

    The SDK default back-off strategy, which increases exponentially up to a max amount of delay. It also applies a larger scale factor upon service throttling exception.

  • DEFAULT_BACKOFF_STRATEGY_V2

    public static final V2CompatibleBackoffStrategy DEFAULT_BACKOFF_STRATEGY_V2

    The SDK default back-off strategy, which increases exponentially up to a max amount of delay. It also applies a larger scale factor upon service throttling exception.

  • DYNAMODB_DEFAULT_BACKOFF_STRATEGY

    public static final RetryPolicy.BackoffStrategy DYNAMODB_DEFAULT_BACKOFF_STRATEGY

    The default back-off strategy for DynamoDB client, which increases exponentially up to a max amount of delay. Compared to the SDK default back-off strategy, it applies a smaller scale factor.

  • getDefaultBackoffStrategy

    public static RetryPolicy.BackoffStrategy getDefaultBackoffStrategy(RetryMode retryMode)

  • getDefaultRetryPolicy

    public static RetryPolicy getDefaultRetryPolicy()

    Returns the SDK default retry policy. This policy will honor the maxErrorRetry set in ClientConfiguration.

    See Also:

    ClientConfiguration.setMaxErrorRetry(int)

  • getDynamoDBDefaultRetryPolicy

    public static RetryPolicy getDynamoDBDefaultRetryPolicy()

    Returns the default retry policy for DynamoDB client. This policy will honor the maxErrorRetry set in ClientConfiguration. For DynamoDB the Default max error retry attempts is kept same as Standard Max retry of Dynamo DB. Thus honorDefaultMaxErrorRetryInRetryMode is set to False so that it uses max error retries same as DYNAMODB_STANDARD_DEFAULT_MAX_ERROR_RETRY which is 10.

    See Also:

    ClientConfiguration.setMaxErrorRetry(int)

  • getDefaultRetryPolicyWithCustomMaxRetries

    public static RetryPolicy getDefaultRetryPolicyWithCustomMaxRetries(int maxErrorRetry)

    Returns the SDK default retry policy with the specified max retry count.

  • getDynamoDBDefaultRetryPolicyWithCustomMaxRetries

    public static RetryPolicy getDynamoDBDefaultRetryPolicyWithCustomMaxRetries(int maxErrorRetry)

    Returns the default retry policy for DynamoDB client with the specified max retry count.
