Note

  • Bucket PUTs: To accommodate processes that require repeated PUT Bucket operations to succeed, Gateway responds with 409 Conflict for repeated requests, regardless of bucket ownership. This differs from Amazon S3 behavior, which returns 403 Forbidden for non-owners. To support processes that require repeated bucket PUT requests to succeed, those requests return 409 Conflict, regardless of owner. This differs from AWS S3 behavior, which returns 403 Forbidden for non-owners.

Important

  • Checksums: Gateway supports all Amazon S3 checksum features except CRC64, which is currently not supported. Refer Supported Amazon S3 Features for more information.

  • Amazon has made CRC64 the default checksum algorithm. If you are using the AWS CLI, specify --checksum-algorithm CRC32C to avoid compatibility issues.
