> ---------------------------------------------------------------
>
> Key: HDDS-5450
> URL: https://issues.apache.org/jira/browse/HDDS-5450
> Project: Apache Ozone
> Issue Type: Improvement
> Components: OM, S3
> Reporter: Bharat Viswanadham
> Assignee: Bharat Viswanadham
> Priority: Major
>
> S3 head uses OM API lookup key which refreshes pipeline info by contacting SCM.
> For S3 head we donot require any pipeline info, we need very basic details like length, type, etag.
> By removing pipeline info which is not required for HEAD object, HEAD API performance can be improved.
> This is identified during looking up graphs from @Ritesh Shukla testing
