      • DISABLE_CERT_CHECKING_SYSTEM_PROPERTY

        public static final String DISABLE_CERT_CHECKING_SYSTEM_PROPERTY
        Disable validation of server certificates when using the HTTPS protocol. This should ONLY be used to do quick smoke tests against endpoints which don't yet have valid certificates; it should NEVER be used in production. This property is meant to be used as a flag (i.e. -Dcom.amazonaws.sdk.disableCertChecking) rather then taking a value (-Dcom.amazonaws.sdk.disableCertChecking=true). This property is treated as false by default (i.e. check certificates by default)

      • DEFAULT_METRICS_SYSTEM_PROPERTY

        public static final String DEFAULT_METRICS_SYSTEM_PROPERTY
        System property used when starting up the JVM to enable the default metrics collected by the AWS SDK, which uploads the derived statistics to Amazon CloudWatch. 
         Example:
  -Dcom.amazonaws.sdk.enableDefaultMetrics

      • EC2_METADATA_SERVICE_OVERRIDE_SYSTEM_PROPERTY

      • RETRY_THROTTLING_SYSTEM_PROPERTY

        public static final String RETRY_THROTTLING_SYSTEM_PROPERTY
        System property for enabling retry throttling.

        Retry throttling is a feature which intelligently throttles retry attempts when a large percentage of requests are failing and retries are unsuccessful, particularly in scenarios of degraded service health. In these situations the client will drain its internal retry capacity and slowly roll off from retry attempts until requests begin to succeed again. At that point the retry capacity pool will begin to refill and retries will once again be permitted

        In situations where retries have been throttled this feature will effectively result in fail-fast behavior from the client. Because retries are circumvented exceptions will be immediately returned to the caller if the initial request is unsuccessful. This will result in a greater number of exceptions being returned up front but prevents requests being tied up attempting subsequent retries which are also likely to fail.

      • REGIONS_FILE_OVERRIDE_SYSTEM_PROPERTY

        public static final String REGIONS_FILE_OVERRIDE_SYSTEM_PROPERTY
        Path to an override file for the region metadata loaded by the SDK that maps service/region pairs to endpoints and vice versa.
        See Also:
        Constant Field Values

      • DISABLE_REMOTE_REGIONS_FILE_SYSTEM_PROPERTY

        public static final String DISABLE_REMOTE_REGIONS_FILE_SYSTEM_PROPERTY
        By default, the SDK will attempt to download an up-to-date set of region metadata from Amazon CloudFront when first required. This allows you to look up information about new regions and services without having to download a new version of the SDK every time.

        If the SDK cannot download region metadata from Amazon CloudFront, it will fall back to loading the region metadata bundled with the SDK when it was released, which may be out of date.

        Setting this system property to anything other than null will disable this remote fetching, and will only load region metadata that was bundled with the SDK. This gives you control over when new region metadata will be picked up by your application, and isolates you from potential issues if your application depends on being able to load metadata about a region which is not included in your version of the SDK and therefore may not be available in the event of network outages.

      • ENABLE_S3_SIGV4_SYSTEM_PROPERTY

        @Deprecated
public static final String ENABLE_S3_SIGV4_SYSTEM_PROPERTY
        Deprecated.
        By default, the AmazonS3Client will continue to use the legacy S3Signer to authenticate requests it makes to S3 in regions that support the older protocol. Setting this property to anything other than null will cause the client to upgrade to Signature Version 4 whenever it has been configured with an explicit region (which is a required parameter for Signature Version 4). The client will continue to use the older signature protocol when not configured with a region to avoid breaking existing applications.

        Signature Version 4 is more secure than the legacy S3Signer, but requires calculating a SHA-256 hash of the entire request body which can be expensive for large upload requests.

      • ENFORCE_S3_SIGV4_SYSTEM_PROPERTY

        @Deprecated
public static final String ENFORCE_S3_SIGV4_SYSTEM_PROPERTY
        Deprecated.
        Like ENABLE_S3_SIGV4_SYSTEM_PROPERTY, but causes the client to always use Signature Version 4, assuming a region of "us-east-1" if no explicit region has been configured. This guarantees that the more secure authentication protocol will be used, but will cause authentication failures in code that accesses buckets in regions other than US Standard without explicitly configuring a region.

      • ENABLE_IN_REGION_OPTIMIZED_MODE

        public static final String ENABLE_IN_REGION_OPTIMIZED_MODE
        Overrides the client default ClientConfiguration to use configuration with values tailored towards clients operating in the same AWS region as the service endpoint they call. Timeouts in in-region optimized configurations are generally set much lower than the client standard configuration.
