Duong commented on HDDS-6996:
-----------------------------
Resolving. All key lookup (head/get) no longer call getBucket or getVolume.
> Perf: Ozone should avoid calling getBucketInfo/getVolInfo for each lookup

> ObjectEndPoint::head shouldn't make a call to getBucket. If it is mandatory,
> it will be nice to introduce a guava cache to reduce the expensive lookup.
> Note that there wouldn't be millions of buckets in the volume. So having
> guava cache with TTL will be nice to have.
