Primarily for historical reasons, ingestion is split into a few components.

#### ConfigStore

The `ConfigStore` reads a variety of resources and exposes them over a standard interface (Get, List, etc). These types are wrapped in a common `config.Config` struct, contrasting with typical Kubernetes clients which use per-resource types. The most common is reading from Kubernetes via the `crdclient` package.

**FastAPI**は<a href="https://docs.pydantic.dev/" class="external-link" target="_blank"><strong>Pydantic </strong></a>と完全に互換性があります（そしてベースになっています）。したがって、追加のPydanticコードがあれば、それも機能します。

データベースのために<abbr title = "Object-Relational Mapper">ORM</abbr>sや、<abbr title = "Object-Document Mapper">ODM</abbr>sなどの、Pydanticに基づく外部ライブラリを備えています。

これは、すべてが自動的に検証されるため、多くの場合、リクエストから取得したオブジェクトを**データベースに直接**渡すことができるということを意味しています。

同じことがその逆にも当てはまり、多くの場合、データベースから取得したオブジェクトを**クライアントに直接**渡すことができます。
