没有前人的工作，就不会有 **FastAPI**。

在它诞生之前，已经有许多工具为其提供了灵感。

我曾经多年避免创建一个新框架。起初，我尝试用许多不同的框架、插件和工具来解决 **FastAPI** 所覆盖的全部功能。

但在某个时刻，除了创造一个能提供所有这些功能的东西之外，别无选择；它要吸收以往工具的最佳理念，并以尽可能好的方式组合起来，利用之前都不存在的语言特性（Python 3.6+ 类型提示）。

## 先前的工具 { #previous-tools }

### [Django](https://www.djangoproject.com/) { #django }

它是最流行且被广泛信任的 Python 框架。被用于构建 Instagram 等系统。

它与关系型数据库（如 MySQL、PostgreSQL）耦合相对紧密，因此若要以 NoSQL 数据库（如 Couchbase、MongoDB、Cassandra 等）作为主要存储引擎并不容易。

   * {@code join("-", 1.0f, 2.0f, 3.0f)} returns the string {@code "1.0-2.0-3.0"}.
   *
   * <p>Note that {@link Float#toString(float)} formats {@code float} differently in GWT. In the
   * previous example, it returns the string {@code "1-2-3"}.
   *
   * @param separator the text that should appear between consecutive values in the resulting string
   *     (but not at the start or end)

  private final TearDownStack tearDownStack = new TearDownStack();

  // NOTE: All durations in these tests are expressed in milliseconds
  @Override
  protected void setUp() {
    // Clear any previous interrupt before running the test.
    if (Thread.currentThread().isInterrupted()) {
      throw new AssertionError(
          "Thread interrupted on test entry. "

        // Simple connectivity test
        return client != null && client.isConnected();
    }
    
    private void reregisterNotifications() {
        // Re-register all previous registrations
        // Implementation would store registration details for recovery
    }
}
```

### 8.2 Network Partition Handling
```java
public class WitnessNetworkPartitionHandler {

 * If you use masked losses with Keras the loss values may be different in TensorFlow `2.12` compared to previous versions.
 * In cases where the mask was previously ignored, you will now get an error if you pass a mask with an incompatible shape.

   * {@code join("-", 1.0, 2.0, 3.0)} returns the string {@code "1.0-2.0-3.0"}.
   *
   * <p>Note that {@link Double#toString(double)} formats {@code double} differently in GWT
   * sometimes. In the previous example, it returns the string {@code "1-2-3"}.
   *
   * @param separator the text that should appear between consecutive values in the resulting string
   *     (but not at the start or end)

**컨테이너당 여러 프로세스**를 실행한다면, 시작되는 프로세스 수가 사용 가능한 것보다 **더 많은 메모리를 소비하지** 않는지 확인해야 합니다.

## 시작 전 단계와 컨테이너 { #previous-steps-before-starting-and-containers }

컨테이너(예: Docker, Kubernetes)를 사용한다면, 사용할 수 있는 주요 접근 방식은 두 가지입니다.

### 여러 컨테이너 { #multiple-containers }

 *     Ordering.natural()
 *         .nullsFirst()
 *         .onResultOf(getBarFunction)
 *         .nullsLast();
 * }
 *
 * Note that each chaining method returns a new ordering instance which is backed by the previous
 * instance, but has the chance to act on values <i>before</i> handing off to that backing instance.
 * As a result, it usually helps to read chained ordering expressions <i>backwards</i>. For example,

		creds:            creds,
	})
	var prevResult madmin.SpeedTestResult
	for {
		select {
		case <-ctx.Done():
			return
		case <-keepAliveTicker.C:
			// if previous result is set keep writing the
			// previous result back to the client
			if prevResult.Version != "" {
				if err := enc.Encode(prevResult); err != nil {
					return
				}
			} else {

- hyperkube: Use debian-hyperkube-base@v1.1.0 image
  
    A previous release built hyperkube using the debian-hyperkube-base@v1.0.0,
    which was updated to address a CVE in the CNI plugins.
    
    A side-effect of using this new image was that the networking packages
