# Persistent Handles Feature - Detailed Design Document

## 1. Overview

Persistent handles (also known as durable handles) allow SMB3 connections to survive network disconnections, server reboots, and client reconnections. This feature is critical for enterprise reliability and seamless failover scenarios.

## 2. Protocol Specification Reference

データベースのために<abbr title = "Object-Relational Mapper">ORM</abbr>sや、<abbr title = "Object-Document Mapper">ODM</abbr>sなどの、Pydanticに基づく外部ライブラリを備えています。

これは、すべてが自動的に検証されるため、多くの場合、リクエストから取得したオブジェクトを**データベースに直接**渡すことができるということを意味しています。

同じことがその逆にも当てはまり、多くの場合、データベースから取得したオブジェクトを**クライアントに直接**渡すことができます。

   * - The map has not switched to delegating to a java.util implementation to mitigate hash

   * methods. But that is a bit too painful....
