# SMB3 Lease Feature - Detailed Design Document

## 1. Overview

SMB3 leases provide a client caching mechanism that replaces the traditional oplock mechanism. Leases enable better performance through client-side caching while maintaining cache coherency across multiple clients.

## 2. Protocol Specification Reference

- **MS-SMB2 Section 2.2.13**: SMB2 CREATE Request with Lease Context
- **MS-SMB2 Section 2.2.14**: SMB2 CREATE Response with Lease State

deklariert wird, beispielsweise wenn mehrere Abhängigkeiten eine gemeinsame Unterabhängigkeit haben, wird **FastAPI** diese Unterabhängigkeit nur einmal pro Request aufrufen.

Und es speichert den zurückgegebenen Wert in einem <abbr title="Mechanismus, der bereits berechnete/generierte Werte zwischenspeichert, um sie später wiederzuverwenden, anstatt sie erneut zu berechnen.">„Cache“</abbr> und übergibt diesen gecachten Wert an alle „Dependanten“, die ihn in diesem spezifischen Request benötigen,...

 * Implementations of this interface will be discovered through the Java ServiceLoader mechanism

Cette image est dotée d'un mécanisme d'"auto-tuning", de sorte qu'il vous suffit d'ajouter votre code pour obtenir automatiquement des performances très élevées. Et sans faire de sacrifices.
