----------------------------------------
Summary: S3 Head uses lookupKey avoid refreshes pipeline to
improve perf
Key: HDDS-5450
URL: https://issues.apache.org/jira/browse/HDDS-5450
Project: Apache Ozone
Issue Type: Improvement
Reporter: Bharat Viswanadham
Assignee: Bharat Viswanadham
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
