conversion">serialization</abbr>" which is taking data from the code (Python) and converting it into something that can be sent through the network. For example, converting an object containing data from a database into a JSON object. Converting `datetime` objects into strings, etc.

Another big feature needed by APIs is data validation, making sure that the data is valid, given certain parameters. For example, that some field is an `int`, and not some random string. This is especially useful for...

  - *apiserver_cache_list_fetched_objects_total*: Counter of objects read from watch cache in the course of serving a LIST request, broken down by resource_prefix and index_name
  - *apiserver_cache_list_evaluated_objects_total*: Counter of objects tested in the course of serving a LIST request from watch cache, broken down by resource_prefix

// itself cannot login, but the policy associated with them determines the base

// - from `Subject.CommonName` field from the STS request for

// has the same name as the value of this field.

// The []journal contains all the different versions of the object.

// ``delete``: This is the delete-marker

Nhưng mặc định, tất cả **đều hoạt động**.

### Validation

* Validation cho đa số (hoặc tất cả?) **các kiểu dữ liệu** Python, bao gồm:
    * JSON objects (`dict`).
    * Mảng JSON (`list`) định nghĩa kiểu dữ liệu từng phần tử.
    * Xâu (`str`), định nghĩa độ dài lớn nhất, nhỏ nhất.
    * Số (`int`, `float`) với các giá trị lớn nhất, nhỏ nhất, etc.
