llm-config-storage

Persistent storage backend for LLM Config Manager using embedded Sled database with encryption support.

Features

• Embedded Database: Zero-config Sled database for persistent storage
• Encryption at Rest: Automatic encryption of sensitive configuration data
• ACID Transactions: Atomic, consistent, isolated, durable operations
• Namespace Isolation: Separate storage for different configuration namespaces
• Version History: Store and retrieve historical configuration versions
• Backup & Restore: Built-in backup and restore capabilities

Usage

Add this to your Cargo.toml:

[dependencies]
llm-config-storage = "0.5.0"
llm-config-crypto = "0.5.0"

Basic Example

use llm_config_storage::StorageBackend;
use llm_config_crypto::CryptoManager;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Initialize storage with encryption
    let crypto = CryptoManager::new()?;
    let storage = StorageBackend::open("./data", Some(crypto))?;

    // Store configuration
    storage.put("app.database.url", b"postgres://localhost/mydb").await?;

    // Retrieve configuration
    let value = storage.get("app.database.url").await?;

    Ok(())
}

Namespace Management

// Create namespace-specific storage
let namespace = storage.namespace("production");
namespace.put("api.key", b"secret-key").await?;

Storage Format

• Key-Value Store: Simple and efficient key-value access
• JSON/Binary: Supports both JSON and binary value storage
• Compression: Optional compression for large values
• Encryption: Transparent encryption layer for sensitive data

Performance

Benchmarks on modern hardware:

• Read operations: ~10 µs per key
• Write operations: ~50 µs per key
• Batch writes: ~5000 ops/sec
