> S3G: Avoid calling getS3Volume in PUT_OBJECT_TAGGING
> ----------------------------------------------------
>
> Key: HDDS-16700
> URL: https://issues.apache.org/jira/browse/HDDS-16700
> Project: Apache Ozone
> Issue Type: Sub-task
> Reporter: Chung-En Lee
> Assignee: dino2895
> Priority: Major
>
> Background & Problem
> When applying tags via `PUT /bucket/key?tagging`, S3G queries
> `getS3VolumeContext` before invoking `putObjectTagging` on OM. Setting tags
> is a standalone metadata mutation, making the preparatory volume lookup RPC
> redundant.
> Proposed Solution
> 1. Extend `assumeS3Context=true` to `OmKeyArgs` for object tagging mutations
> on OM.
> 2. Remove the preliminary `getS3VolumeContext` RPC in `ObjectEndpoint#put`
> (tagging path).
> Expected Impact
> Reduces RPC round trips from 2 to 1 for `PutObjectTagging` calls.
