StorageGRID Webscale implements multipart uploads differently from the Amazon S3 REST API.
Operation | Implementation |
---|---|
List Multipart Uploads | The following request headers are supported:
The delimiter request parameter is not supported. |
Initiate Multipart Upload | The x-amz-storage-class request header is supported with the following enumerated values:
Note: Specifying the REDUCED_REDUNDANCY value does not affect the specified ILM policy, and does not result in data being stored at lower levels of redundancy in the StorageGRID Webscale system.
The following request headers are supported:
To record the object creation time, so that you can use the User Defined Creation Time option for the reference time in an ILM rule, you need to store the value in a user-defined header named x-amz-meta-creation-time. For example: x-amz-meta-creation-time=1443399726. This field is evaluated as seconds since Jan 1, 1970. For more information, see "Reference time" in the Administrator Guide. The x-amz-server-side-encryption header is not supported directly for Initiate Multipart Upload requests. If you require server-side encryption for a multipart upload, you need to specify the x-amz-server-side-encryption header for each of the upload parts, but you cannot specify it as part of the Initiate Multipart Upload header or the request fails. The following request headers are not supported and return XNotImplemented:
