}

// load the cache content with name from minioMetaBackgroundOpsBucket.
// Only backend errors are returned as errors.
// The loader is optimistic and has no locking, but tries 5 times before giving up.
// If the object is not found, a nil error with empty data usage cache is returned.

- All versions, including delete-markers should be deleted before deleting a bucket.
- **Versioning feature is only available in erasure coded and distributed erasure coded setups**.

## How to configure versioning on a bucket

Each bucket created has a versioning configuration associated with it. By default bucket is unversioned as shown below

```

				continue
			}
			if endpoint.IsLocal && endpoint.Host != "" {
				peerSet.Add(endpoint.Host)
			}
		}
	}
	if peerSet.IsEmpty() {
		// Local peer can be empty in FS or Erasure coded mode.
		// If so, return globalMinioHost + globalMinioPort value.
		if host != "" {
			return net.JoinHostPort(host, port)
		}

		return net.JoinHostPort("127.0.0.1", port)
	}

		return -1
	}
}

// Returns always a same erasure coded set for a given input.
func (s *erasureSets) getHashedSetIndex(input string) int {
	return hashKey(s.distributionAlgo, input, len(s.sets), s.deploymentID)
}

// Returns always a same erasure coded set for a given input.
func (s *erasureSets) getHashedSet(input string) (set *erasureObjects) {

		clusterAuditMG,
		clusterNotificationMG,
		clusterIAMMG,
	}

	// Bucket metrics are special, they always include the bucket label. These
	// metrics required a list of buckets to be passed to the loader, and the list
	// of buckets is not known until the request is made. So we keep a separate
	// map for bucket metrics and handle them specially.

	// Add the serverName and poolIndex labels to all non-cluster metrics.

NOTE:

- `timeToFirstByte` and `timeToResponse` will be expressed in Nanoseconds.
- Additionally in the case of the erasure coded setup `tags.objectErasureMap` provides per object details about
  - Pool number the object operation was performed on.
  - Set number the object operation was performed on.
