![put](https://raw.githubusercontent.com/minio/minio/master/docs/bucket/versioning/versioning_PUT_versionEnabled.png)

This protects against accidental overwrites or deletes of objects, allows previous versions to be retrieved.

When you DELETE an object, all versions remain in the bucket and MinIO adds a delete marker, as shown below:

![delete](https://raw.githubusercontent.com/minio/minio/master/docs/bucket/versioning/versioning_DELETE_versionEnabled.png)

### Internal metadata for replication

`xl.meta` that is in use for [versioning](https://github.com/minio/minio/blob/master/docs/bucket/versioning/DESIGN.md) has additional metadata for replication of objects,delete markers and versioned deletes.

### Metadata for object replication - on source

```
...
  "MetaSys": {
      "x-minio-internal-inline-data": "dHJ1ZQ==",

You can use the same type declarations with `str`, `float`, `bool` and many other complex data types.

Several of these are explored in the next chapters of the tutorial.

## Order matters { #order-matters }

When creating *path operations*, you can find situations where you have a fixed path.

Like `/users/me`, let's say that it's to get data about the current user.

		},
		{
			name:   "GET key list",
			method: http.MethodGet,
			path:   kmsKeyListPath,
			query:  map[string]string{"pattern": "*"},
		},
		{
			name:   "GET key status",
			method: http.MethodGet,
			path:   kmsKeyStatusPath,
			query:  map[string]string{"key-id": "master-key-id"},
		},
	}

            function.bits(),
            function);
      }
    }

    @Override
    HashCode makeHash(Hasher[] hashers) {
      byte[] bytes = new byte[bits() / 8];
      int i = 0;
      for (Hasher hasher : hashers) {
        HashCode newHash = hasher.hash();
        i += newHash.writeBytesTo(bytes, i, newHash.bits() / 8);
      }
      return HashCode.fromBytesNoCopy(bytes);

mc admin service restart myminio
```

### Using WebIdentiy API

Client ID can be found by clicking any of the clients listed [here](http://localhost:8080/auth/admin/master/console/#/realms/minio/clients). If you have followed the above steps docs, the default Client ID will be `account`.

```

      super(master.size() + 3, MODIFIABLE, master, IteratorTester.KnownOrder.KNOWN_ORDER);
      this.master = master;
    }

    @Override
    protected Iterator<T> newTargetIterator() {
      // make copy from master to verify later
      targetList = Lists.newArrayList(master);
      Iterator<T> iterator = targetList.iterator();
      return peekingIterator(iterator);
    }

    @Override

Sie können für Typdeklarationen auch `str`, `float`, `bool` und viele andere komplexe Datentypen verwenden.

Mehrere davon werden wir in den nächsten Kapiteln erkunden.

## Die Reihenfolge ist wichtig { #order-matters }

Wenn Sie *Pfadoperationen* erstellen, haben Sie manchmal einen fixen Pfad.

Etwa `/users/me`, um Daten über den aktuellen Benutzer zu erhalten.

Puedes usar las mismas declaraciones de tipo con `str`, `float`, `bool` y muchos otros tipos de datos complejos.

Varios de estos se exploran en los siguientes capítulos del tutorial.

## El orden importa { #order-matters }

Al crear *path operations*, puedes encontrarte en situaciones donde tienes un path fijo.

Como `/users/me`, imaginemos que es para obtener datos sobre el usuario actual.
