### Expiry or removal events

An object that is in transition tier will be deleted once the object hits expiry date or if removed via `mc rm` (`mc rm --vid` in the case of delete of a specific object version). Other rules specific to legal hold and object locking precede any lifecycle rules.

### Additional notes

Tiering and lifecycle transition are applicable only to erasure/distributed MinIO.

MinIO server allows WORM for specific objects or by configuring a bucket with default object lock configuration that applies default retention mode and retention duration to all objects. This makes objects in the bucket immutable i.e. delete of the version are not allowed until an expiry specified in the bucket's object lock configuration or object retention.

### Antes y después de la `response`

Puedes añadir código que se ejecute con la `request`, antes de que cualquier *path operation* la reciba.

Y también después de que se genere la `response`, antes de devolverla.

Por ejemplo, podrías añadir un custom header `X-Process-Time` que contenga el tiempo en segundos que tomó procesar la request y generar una response:

  fun initialize() {
    cache.initialize()
  }

  /**
   * Closes the cache and deletes all of its stored values. This will delete all files in the cache
   * directory including files that weren't created by the cache.
   */
  @Throws(IOException::class)
  fun delete() {
    cache.delete()
  }

  /**
   * Deletes all values stored in the cache. In-flight writes to the cache will complete normally,
