you can set the storage class of an object via request metadata field `x-amz-storage-class`. MinIO server then honors the storage class by
saving the object in specific number of data and parity drives.

## Storage usage

The selection of varying data and parity drives has a direct impact on the drive space usage. With storage class, you can optimize for high

// checkCopyPartRangeWithSize adds more check to the range string in case of
// copy object part. This API requires having specific start and end  range values
// e.g. 'bytes=3-10'. Other use cases will be rejected.

Following are advantages for using temporary credentials:

- Eliminates the need to embed long-term credentials with an application.
- Eliminates the need to provide access to buckets and objects without having to define static credentials.
- Temporary credentials have a limited lifetime, there is no need to rotate them or explicitly revoke them. Expired temporary credentials cannot be reused.
