Spark/Hadoop workloads which use Hadoop MR Committer v1/v2 algorithm upload objects to a temporary prefix in a bucket. These objects are 'renamed' to a different prefix on Job commit. Object storage admins are forced to configure separate ILM policies to expire these objects and their versions to reclaim space.

### Solution

To exclude objects under a list of prefix (glob) patterns from being versioned, you can send the following versioning configuration with Status set to `Enabled`.

	if lc == nil && opts.Expiration.Expire {
		if opts.VersionID != "" {
			return objInfo, VersionNotFound{
				Bucket:    bucket,
				Object:    object,
				VersionID: opts.VersionID,
			}
		}
		return objInfo, ObjectNotFound{
			Bucket: bucket,
			Object: object,
		}
	}

	if opts.DeletePrefix {
		if opts.Expiration.Expire {

	Limit        int                      // maximum number of items, 0 means no limit
}

// ExpirationOptions represents object options for object expiration at objectLayer.
type ExpirationOptions struct {
	Expire bool
}

// TransitionOptions represents object options for transition ObjectLayer operation
type TransitionOptions struct {
	Status         string
	Tier           string
	ETag           string
