Harshavardhana d46386246f api: Introduce metadata update APIs to update only metadata (#11962) ... Current implementation heavily relies on readAllFileInfo but with the advent of xl.meta inlined with data, we cannot easily avoid reading data when we are only interested is updating metadata, this leads to invariably write amplification during metadata updates, repeatedly reading data when we are only interested in updating metadata. This PR ensures that we implement a metadata only update API at storage layer, that handles updates to metadata alone for any given version - given the version is valid and present. This helps reduce the chattiness for following calls.. - PutObjectTags - DeleteObjectTags - PutObjectLegalHold - PutObjectRetention - ReplicateObject (updates metadata on replication status)		2021-04-04 13:32:31 -07:00
