### Set object lock

PutObject API allows setting per object retention mode and retention duration using `x-amz-object-lock-mode` and `x-amz-object-lock-retain-until-date` headers. This takes precedence over any bucket object lock configuration w.r.t retention.

apply `STANDARD` storage class to the object. This means the data and parity drives will be used as set in `STANDARD` storage class.

- If storage class is not defined before starting MinIO server, and subsequent PutObject metadata field has `x-amz-storage-class` present
with values `REDUCED_REDUNDANCY` or `STANDARD`, MinIO server uses default parity values.
