>                 Key: HDDS-16698
>                 URL: https://issues.apache.org/jira/browse/HDDS-16698
>             Project: Apache Ozone
>          Issue Type: Sub-task
>            Reporter: Chung-En Lee
>            Assignee: Jheng-Sing Chen
>            Priority: Major
>
> Background & Problem
> Listing active multipart uploads (`GET /bucket?uploads`) or listing uploaded 
> parts (`GET /bucket/key?uploadId=...`) currently requires S3G to execute 
> `getS3VolumeContext` before forwarding the list request to OM.
> Proposed Solution
> 1. Update OM's `ListMultipartUploads` and `ListParts` RPC protocols to 
> support `assumeS3Context=true`.
> 2. Update `BucketEndpoint` and `ObjectEndpoint` multipart listing paths to 
> directly query OM without the precursory volume resolution RPC.
> ### Expected Impact
> Saves 1 RPC round trip on MPU discovery and progress query flows.
