Amazon S3 Multi-Region Access Points
Amazon S3 Multi-Region Access Points provide a global endpoint that applications can use to fulfill requests from Amazon S3 buckets located in multiple AWS Regions. You can use Multi-Region Access Points to build multi-Region applications with the same architecture used in a single Region, and then run those applications anywhere in the world.
To learn more about Multi-Region Access Points, see Multi-Region Access Points in Amazon S3 in the Amazon S3 User Guide.
To learn more about Multi-Region Access Point Amazon Resource Names (ARNs), see Making requests using a Multi-Region Access Point in the Amazon S3 User Guide.
To learn more about creating Multi-Region Access Points, see Managing Multi-Region Access Points in the Amazon S3 User Guide.
The SigV4A algorithm is the signing implementation used to sign the global Region requests. This algorithm is obtained by the SDK through a dependency on the AWS Common Runtime (CRT) libraries.
Configure this functionality by using the following:
s3_disable_multiregion_access_points- shared AWSconfigfile settingAWS_S3_DISABLE_MULTIREGION_ACCESS_POINTS- environment variableaws.s3DisableMultiRegionAccessPoints- JVM system property: Java/Kotlin only- To configure value directly in code, consult your specific SDK directly.
-
This setting controls whether the SDK potentially attempts cross-Region requests. If multiply defined, the code-configured setting takes precedence, followed by the environment variable setting.
Default value:
falseValid values:
-
true– Stops the use of cross-Region requests. -
false– Enables cross-Region requests using Multi-Region Access Points.
