## Concepts

- All Buckets on MinIO are always in one of the following states: unversioned (the default) and all other existing deployments, versioning-enabled, or versioning-suspended.
- Versioning state applies to all of the objects in the versioning enabled bucket. The first time you enable a bucket for versioning, objects in the bucket are thereafter always versioned and given a unique version ID.

// ObjectsVersionCountIntervals is the list of all intervals
// of object version count to be included in objects histogram.
var ObjectsVersionCountIntervals = [dataUsageVersionLen]objectHistogramInterval{
	{"UNVERSIONED", 0, 0},
	{"SINGLE_VERSION", 1, 1},
	{"BETWEEN_2_AND_10", 2, 9},
	{"BETWEEN_10_AND_100", 10, 99},
	{"BETWEEN_100_AND_1000", 100, 999},
	{"BETWEEN_1000_AND_10000", 1000, 9999},

CPU Quota, NodeStatus will contain a warning indicating that CPU Limits cannot
be enforced.
  * The following applies only if you use the Go language client (<code>/pkg/client/unversioned</code>) to create Job by defining Go variables of type "<code>k8s.io/kubernetes/pkg/apis/extensions".Job</code>).  We think <strong>this is not common</strong>, so if you are not sure what this means, you probably aren't doing this.  If

Note that just like with [AWS](https://docs.aws.amazon.com/AmazonS3/latest/userguide/delete-marker-replication.html), Delete marker replication is disallowed in MinIO when the replication rule has tags.

// It returns true if the listing is non-versioned and the given object is expired.
func triggerExpiryAndRepl(ctx context.Context, o listPathOptions, obj metaCacheEntry) (skip bool) {
	versioned := o.Versioning != nil && o.Versioning.Versioned(obj.name)

	// skip latest object from listing only for regular
	// listObjects calls, versioned based listing cannot
	// filter out between versions 'obj' cannot be truncated

	if err != nil {
		return opts, InvalidArgument{
			Bucket: bucket,
			Object: object,
			Err:    err,
		}
	}

	opts.VersionID = vid
	opts.Versioned = versioned
	opts.VersionSuspended = versionSuspended

	// For directory objects skip creating new versions.
	if isDirObject(object) && vid == "" {
		opts.VersionID = nullVersionID
	}

	return opts, nil
}
