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

- 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

```

		XLV1:             false,
		ModTime:          time.Now().UTC(),
		Size:             0,
		Mode:             0,
		Metadata:         nil,
		Parts:            nil,
		Erasure: ErasureInfo{
			Algorithm:    ReedSolomon.String(),
			DataBlocks:   4,
			ParityBlocks: 2,
			BlockSize:    10000,
			Index:        1,
			Distribution: []int{1, 2, 3, 4, 5, 6, 7, 8},

		Results: make([]int, len(fi.Parts)),
	}

	for i, part := range fi.Parts {
		checksumInfo := erasure.GetChecksumInfo(part.Number)
		partPath := pathJoin(volumeDir, path, fi.DataDir, fmt.Sprintf("part.%d", part.Number))
		err := s.bitrotVerify(ctx, partPath,
			erasure.ShardFileSize(part.Size),
			checksumInfo.Algorithm,
			checksumInfo.Hash, erasure.ShardSize())
