# Directory Leasing Feature - Detailed Design Document

## 1. Overview

Directory leasing extends the SMB3 lease concept to directories, enabling client-side caching of directory metadata and change notifications. This significantly improves performance for applications that frequently enumerate directories or monitor directory changes.

## 2. Protocol Specification Reference

- **MS-SMB2 Section 2.2.13.2.12**: SMB2_CREATE_REQUEST_LEASE_V2 for directories

- BucketWebsite (Use [`caddy`](https://github.com/caddyserver/caddy) or [`nginx`](https://www.nginx.com/resources/wiki/))
- BucketAnalytics, BucketMetrics, BucketLogging (Use [bucket notification](https://docs.min.io/community/minio-object-store/administration/monitoring/bucket-notifications.html) APIs)
