- Significant kube-proxy performance improvements for non UDP ports. ([#83208](https://github.com/kubernetes/kubernetes/pull/83208), [@robscott](https://github.com/robscott))

Temel özellikleri şunlardır:

* **Hızlı**: Çok yüksek performanslı, **NodeJS** ve **Go** ile eşit düzeyde (Starlette ve Pydantic sayesinde). [Mevcut en hızlı Python framework'lerinden biri](#performance).
* **Kodlaması Hızlı**: Özellik geliştirme hızını yaklaşık %200 ile %300 aralığında artırır. *
* **Daha az hata**: İnsan (geliştirici) kaynaklı hataları yaklaşık %40 azaltır. *

   * to consider using {@link #forEachPair} instead of this method.
   *
   * <p><b>Performance note:</b> The resulting stream is not <a
   * href="http://gee.cs.oswego.edu/dl/html/StreamParallelGuidance.html">efficiently splittable</a>.
   * This may harm parallel performance.

 * the columns. The reverse is also available, associating a column with a row key / value map. Note
 * that, in some implementations, data access by column key may have fewer supported operations or
 * worse performance than data access by row key.
 *
 * <p>The methods returning collections or maps always return views of the underlying table.
 * Updating the table can change the contents of those collections, and updating the collections

 *
 * <p>The returned map is implemented as a hash table with similar performance characteristics to
 * {@link ConcurrentHashMap}. It supports all optional operations of the {@code ConcurrentMap}
 * interface. It does not permit null keys or values.

FastAPI は、Python の標準である型ヒントに基づいて Python 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）。 [利用可能な最も高速な Python フレームワークの一つです](#performance)。
* **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。*
* **直感的**: 素晴らしいエディタサポート。<dfn title="別名: auto-complete、autocompletion、IntelliSense">補完</dfn> があらゆる場所で使えます。デバッグ時間を削減します。
