S3_EXPRESS_BUCKET business metric feature implementation that tracks when an operation called using the S3 Express feature.

Motivation and Context

Adding business metrics for feature IDs to track S3 Express (feature ID "J") usage in AWS SDK S3 requests. This tracks customer adoption of these S3 feature.

When the bucket name matches S3 Express Ruleset and express credentials are used, the SDK SHOULD track a business metric.

Modifications

• Added S3ExpressUtils.addS3ExpressBusinessMetricIfApplicable() utility method that adds S3_EXPRESS_BUCKET business metric (feature ID "J") when both S3 Express endpoint resolution and S3 Express auth scheme are used.

• Modified EndpointResolverInterceptorSpec code generation to call the S3 Express business metrics method during endpoint resolution for S3 service

Testing

• Added functional tests to verify User-Agent header contains correct business metric when S3ExpressBucket is used.
