Assignee: Jheng-Sing Chen
> S3G: Avoid calling getS3Volume in GET_BUCKET (ListObjects)
> ----------------------------------------------------------
>
> Key: HDDS-16696
> URL: https://issues.apache.org/jira/browse/HDDS-16696
> Project: Apache Ozone
> Issue Type: Sub-task
> Reporter: Chung-En Lee
> Assignee: Jheng-Sing Chen
> Priority: Major
>
> Background & Problem
> In `BucketEndpoint#get`, S3G handles S3 bucket listing requests. Before
> asking OM to `listKeys` or `listStatus`, S3G currently call a
> `getS3VolumeContext` RPC to resolve the volume associated with the S3 bucket.
> Proposed Solution
> 1. Update `ListKeys` / `ListStatus` protocol on OM to accept
> `assumeS3Context=true` (or resolve S3 bucket mappings natively).
> 2. Refactor `BucketEndpoint` to invoke OM listing directly without executing
> the prior `getS3VolumeContext` RPC.
> Expected Impact
> - Eliminates 1 RTT from bucket listing operations.
> - Reduces S3G thread holding time during heavy listing workloads.
