## Implementation

ILM tiering takes place when a object placed in the bucket meets lifecycle transition rules and becomes eligible for tiering. MinIO scanner (which runs at one minute intervals, each time scanning one sixteenth of the namespace), picks up the object for tiering. The data is moved to the remote tier in entirety, leaving only the object metadata on MinIO.

func (n NoncurrentVersionTransition) NextDue(obj ObjectOpts) (time.Time, bool) {
	if obj.IsLatest || n.StorageClass == "" {
		return time.Time{}, false
	}
	// Days == 0 indicates immediate tiering, i.e object is eligible for tiering since it became noncurrent.
	if n.NoncurrentDays == 0 {
		return obj.SuccessorModTime, true
	}
	return ExpectedExpiryTime(obj.SuccessorModTime, int(n.NoncurrentDays)), true

	if !obj.IsLatest || t.IsNull() {
		return time.Time{}, false
	}

	if !t.IsDateNull() {
		return t.Date.Time, true
	}

	// Days == 0 indicates immediate tiering, i.e object is eligible for tiering since its creation.
	if t.Days == 0 {
		return obj.ModTime, true
	}
	return ExpectedExpiryTime(obj.ModTime, int(t.Days)), true
