### Checking cluster health for maintenance

You may query the cluster probe endpoint to check if the node which received the request can be taken down for maintenance, if the server replies back '412 Precondition Failed' this means you will lose HA. '200 OK' means you are okay to proceed.

* Zeer indrukwekkende prestaties. Het is <a href="https://github.com/encode/starlette#performance" class="external-link" target="_blank">een van de snelste Python frameworks, vergelijkbaar met **NodeJS** en **Go**</a>.
* **WebSocket** ondersteuning.
* Taken in de achtergrond tijdens het proces.
* Opstart- en afsluit events.
* Test client gebouwd op HTTPX.
* **CORS**, GZip, Statische bestanden, Streaming reacties.

FastAPI は、Pythonの標準である型ヒントに基づいてPython 以降でAPI を構築するための、モダンで、高速(高パフォーマンス)な、Web フレームワークです。

主な特徴:

- **高速**: **NodeJS** や **Go** 並みのとても高いパフォーマンス (Starlette と Pydantic のおかげです)。 [最も高速な Python フレームワークの一つです](#_10).

- **高速なコーディング**: 開発速度を約 200%~300%向上させます。 \*
- **少ないバグ**: 開発者起因のヒューマンエラーを約 40％削減します。 \*
