I am trying to fetch all the folders under AWS organizations recursively but getting following throttling exception intermittently.

com.amazonaws.services.organizations.model.TooManyRequestsException: AWS Organizations can't complete your request because another request is already in progress. Try again later.

I tried configuring retry while creating AWS client itself by referring AWS Docs andd added following to the code:

PredefinedBackoffStrategies.EqualJitterBackoffStrategy jitterBackoffStrategy = new PredefinedBackoffStrategies.EqualJitterBackoffStrategy(
                awsClientConfig.getBaseDelayBeforeNextRetryInMills(), awsClientConfig.getMaxBackoffTimeInMills());

        RetryPolicy retryPolicy = new RetryPolicy
                .RetryPolicyBuilder()
                .withBackoffStrategy(jitterBackoffStrategy)
                .withMaxErrorRetry(awsClientConfig.getMaxRetries())
                .withHonorMaxErrorRetryInClientConfig(false)
                .build();

        ClientConfiguration clientConfiguration = new ClientConfiguration()
                .withProtocol(Protocol.HTTPS)
                .withRetryPolicy(retryPolicy)
                .withProxyHost(proxyConfiguration.getHost())
                .withProxyPort(proxyConfiguration.getPort())
                .withConnectionTimeout(awsClientConfig.getConnectTimeoutInMills());

        AWSOrganizations client =  AWSOrganizationsClientBuilder.standard()
                .withClientConfiguration(clientConfiguration)
                .withCredentials(new AWSStaticCredentialsProvider(new BasicSessionCredentials(
                        Credentials().getAccessKeyId(),
                        Credentials().getSecretAccessKey(),
                        Credentials().getSessionToken())))
                .withRegion(region)
                .build();

But I am not able to figure out that while AWS client reties internally, will it throw above exception evert time. For instance, if I have set max_retry = 3 will the above exception (I am catching it when calling listRoot API of AWS SDK) be printed 3 times or SDK will throw it only once after all the reties are done.

Also is there any way we can log all the retries of AWS SDK.
