## Proxy implementation

In its initial implementations, the ztunnel was actually implemented in 3 different ways: a bespoke Rust implementation, a bespoke Go implementation, and in Envoy.

In the end, [after evaluation](https://docs.google.com/document/d/1c2123cKuYsBDpIon9FFdctWTUIMFweSjgwG7r8l3818/edit), the decision was to move forward with a Rust implementation.

 *
 * <p>The tested methods and constructors are invoked -- each time with one parameter being null and
 * the rest not null -- and the test fails if no expected exception is thrown. {@code
 * NullPointerTester} uses best effort to pick non-null default values for many common JDK and Guava
 * types, and also for interfaces and public classes that have public parameter-less constructors.

3. Kopiere die Datei mit den Paketanforderungen in das Verzeichnis `/code`.

    Kopieren Sie zuerst **nur** die Datei mit den Anforderungen, nicht den Rest des Codes.

    Da sich diese Datei **nicht oft ändert**, erkennt Docker das und verwendet den **Cache** für diesen Schritt, wodurch der Cache auch für den nächsten Schritt aktiviert wird.

// Retry unit interval
var lockRetryMinInterval time.Duration

var lockRetryBackOff func(*rand.Rand, uint) time.Duration

func init() {
	// Check for MINIO_DSYNC_TRACE env variable, if set logging will be enabled for failed REST operations.
	dsyncLog = env.Get("_MINIO_DSYNC_TRACE", "0") == "1"

	lockRetryMinInterval = 250 * time.Millisecond
	if lri := env.Get("_MINIO_LOCK_RETRY_INTERVAL", ""); lri != "" {
		v, err := strconv.Atoi(lri)

Voor nu hoef je alleen te weten dat `Annotated` bestaat en dat het standaard Python is. 😎

Later zul je zien hoe **krachtig** het kan zijn.

	adminAPI := adminAPIHandlers{}
	// Admin router
	adminRouter := router.PathPrefix(adminPathPrefix).Subrouter()

We will create a FastAPI **dependency** with `yield` that will provide a new `Session` for each request. This is what ensures that we use a single session per request. 🤓

Then we create an `Annotated` dependency `SessionDep` to simplify the rest of the code that will use this dependency.

## パフォーマンス

独立した TechEmpower のベンチマークでは、Uvicorn で動作する**FastAPI**アプリケーションが、<a href="https://www.techempower.com/benchmarks/#section=test&runid=7464e520-0dc2-473d-bd34-dbdfd7e85911&hw=ph&test=query&l=zijzen-7" class="external-link" target="_blank">Python フレームワークの中で最も高速なものの 1 つ</a>であり、Starlette と Uvicorn（FastAPI で内部的に使用されています）にのみ下回っていると示されています。
