Duong updated HDDS-9447:
------------------------
Description:
Today, for S3 use case getKeyInfo API needs to look up S3 volume context as the
S3 client doesn't know the exact S3 volume. This is done as an optimization
that liberates S3 from the need to make an extra call to 'GetS3Volume' per GET
key (HDDS-7324).
Ref:
[https://github.com/apache/ozone/blob/master/hadoop-ozone/ozone-manager/src/main/java/org/apache/hadoop/ozone/om/OmMetadataReader.java#L160-L169]
This getS3VolumeContext contributes to around 30% of getKeyInfo for S3 and
creates a performance gap between S3 use case and FSO use case.
Inside getS3VolumeContext, there's an ACL check to validate the client user has
access to the S3 volume.
