Module sled_backend 

Sled embedded database storage backend

This module provides a production-ready implementation of the Storage and KeyValueStorage traits using the Sled embedded database. Sled is a high-performance, log-structured merge tree (LSM) based embedded database that provides ACID guarantees through compare-and-swap operations.

Features

• Embedded database with no external dependencies
• ACID transactions with compare-and-swap
• Prefix scanning and range queries
• Automatic compaction and cleanup
• Crash-safe with write-ahead logging
• Compression support
• Thread-safe operations
• Zero-copy reads where possible

Architecture

The backend uses separate Sled trees for each table, with a metadata tree for statistics and versioning. All operations are wrapped to provide async interfaces while Sled itself operates synchronously.
