Amazon S3 Express One Zone now supports atomic renaming of objects with a single API call

Amazon S3 Express One Zone now supports renaming objects with the new RenameObject API. For the first time in S3, you can rename existing objects atomically (with a single operation) without any data movement.

The RenameObject API simplifies data management in S3 directory buckets by transforming a multi-step rename operation into a single API call. You can now rename objects in S3 Express One Zone by specifying an existing object’s name as the source and the new name of the object as the destination within the same S3 directory bucket. With no data movement involved, this capability accelerates applications like log file management, media processing, and data analytics while lowering costs. For example, renaming a 1-terabyte log file can now complete in milliseconds, instead of hours, significantly accelerating applications and reducing cost.

You can use the RenameObject API in the S3 Express One Zone storage class in all AWS Regions where the storage class is available. You can get started with the new capability in S3 Express One Zone using the AWS SDKs, AWS CLI, AWS Management Console, Amazon S3 API, or Mountpoint for Amazon S3 (version 1.19.0 or higher).
