// Manual index creation
db.createIndex('users', 'email');    // Fast email lookups
db.createIndex('users', 'age');      // Fast age range queries
db.createIndex('orders', 'userId');  // Fast user order lookups

// Auto-indexing via schema
db.createTable('products', {
    id: { type: 'number', required: true, indexed: true },
    name: { type: 'string', indexed: false },
    category: { type: 'string', indexed: true },     // Auto-indexed
    price: { type: 'number', indexed: true },        // Auto-indexed
    inStock: { type: 'boolean', indexed: false }
});

📊 Performance Monitoring

Track and optimize your database performance:

// Get detailed performance metrics
const metrics = db.getPerformanceMetrics();
console.log(metrics);
// {
//   averageQueryTime: '0.45ms',
//   totalQueries: 1250,
//   indexUsage: 892,
//   cacheHitRate: 0.85,
//   tablesWithIndexes: 3,
//   totalIndexes: 8
// }

// Built-in benchmarking
await db.benchmark(100000);  // Test with 100K records
// 🏆 BENCHMARK RESULTS:
// ├─ Array Search: 45.67ms (2,456 results)

// ├─ 🚄 Speed Improvement: 37.1x faster
// └─ 📈 Efficiency Gain: 97.3% improvement

⚡ Optimized Bulk Operations

Handle large datasets efficiently:

// Performance-optimized bulk insert
const largeDataset = generateMillionRecords();

console.time('Bulk Insert');
await db.bulkInsert('analytics', largeDataset);
console.timeEnd('Bulk Insert');
// Bulk Insert: 2,345ms (1M records with chunking)

// Lightning-fast indexed queries on large datasets
const results = await db.whereOperator('score', '>', 800)
                       .where('category', 'premium')
                       .limit(100)
                       .get('analytics');
// Query time: 0.8ms (on 1M records with indexes)

🧠 Memory Management for Large Datasets

Rockdex DB intelligently manages memory to prevent browser crashes:

// Automatic chunking and streaming for large datasets
const db = new RockdexDB({
    chunkSize: 10000,      // 10K records per chunk
    maxMemoryChunks: 5     // Keep max 5 chunks in RAM
});

// Process millions of records without memory issues
db.setTable('bigdata', millionRecords);
// ✅ Automatically chunked into manageable pieces
// ✅ LRU eviction prevents memory overflow
// ✅ Lazy loading for optimal performance

📈 Performance Comparison

Results may vary based on data complexity and system specs

🚀 Quick Start

Installation

npm install @odion-cloud/rockdex-db

Basic Usage

const RockdexDB = require('@odion-cloud/rockdex-db');

// Create database instance
const db = new RockdexDB({
    storageMode: 'memory',
    logging: true
});

// Create table and insert data
db.createTable('users');
db.insert('users', {
    name: 'John Doe',
    email: '[email protected]',
    age: 30
});

// Query with advanced conditions
const adults = db
    .whereOperator('age', '>=', 18)
    .orderBy('name')
    .get('users');

console.log('Adult users:', adults);

🎯 Storage Modes

Memory Mode (Default)

Perfect for temporary data, caching, and development:

const db = new RockdexDB({
    storageMode: 'memory',
    logging: true,
    timestamps: true
});

// Create tables and add data
db.createTable('users');
db.insert('users', {
    name: 'Alice Smith',
    email: '[email protected]'
});

File Mode with Manual Tables

For persistent storage with complete control:

// 1. Create your database structure manually
mkdir ./database
touch ./database/users.rdb
touch ./database/posts.rdb  
touch ./database/orders.rdb

// 2. Configure Rockdex DB
const db = new RockdexDB({
    storageMode: 'file',
    storagePath: './database',
    storageTable: ['users.rdb', 'posts.rdb', 'orders.rdb']
});

await db.ready(); // Wait for initialization

📚 Core Features

Schema Validation

const userSchema = {
    name: { type: 'string', required: true },
    email: { type: 'string', required: true, pattern: /@/ },
    age: { type: 'number', min: 0, max: 120 },
    role: { type: 'string', required: false }
};

db.createTable('users', userSchema);

// This will validate against schema
db.insert('users', {
    name: 'John', 
    email: '[email protected]',
    age: 30 
});

Advanced Queries

// Complex WHERE conditions
const results = db
    .where('age', 25)
    .whereOperator('salary', '>', 50000)
    .whereIn('department', ['IT', 'HR'])
    .whereLike('name', 'John%')
    .orderBy('salary', 'DESC')
    .limit(10, 0)
    .get('employees');

// Aggregations
const avgSalary = db.avg('employees', 'salary');
const totalSales = db.sum('orders', 'amount');
const maxPrice = db.max('products', 'price');

// Grouping
const usersByDepartment = db.groupBy('employees', 'department');

Transactions

db.transaction(db => {
    db.insert('users', userData);
    db.insert('profiles', profileData);
    // If any operation fails, all changes are rolled back
});

Triggers

db.createTrigger('users', 'beforeInsert', ({ operation, NEW }) => {
    NEW.created_at = new Date().toISOString();
    return true; // Allow operation
});

db.createTrigger('users', 'afterUpdate', ({ operation, OLD, NEW }) => {
    console.log(`User ${OLD.name} updated to ${NEW.name}`);
});

🔄 Export/Import Workflow

Export Data

// Browser: Downloads file automatically
db.exportTable('users');

// Node.js: Get export string to save manually
const userData = db.getTableExport('users');
// fs.writeFileSync('./database/users.rdb', userData);

Import Data

// Load data from .rdb file content
const fileContent = fs.readFileSync('./database/users.rdb', 'utf8');
db.importTable('users', fileContent);

🌐 Browser Usage

<!DOCTYPE html>
<html>
<head>
    <script src="rockdex-db.min.js"></script>
</head>
<body>
    <script>
        const db = new RockdexDB({
            storageMode: 'file',
            storageTable: ['users.rdb', 'posts.rdb']
        });
        
        db.createTable('users');
        db.insert('users', { name: 'Browser User' });
        
        // Export table - automatically downloads .rdb file
        db.exportTable('users');
    </script>
</body>
</html>

🔒 Manual Encryption Example

Users handle encryption before storing sensitive data:

// Simple encryption functions (use proper crypto libraries in production)
function encrypt(data, key) {
    return Buffer.from(JSON.stringify(data)).toString('base64');
}

function decrypt(encryptedData, key) {
    return JSON.parse(Buffer.from(encryptedData, 'base64').toString('utf8'));
}

// Encrypt before storing
const sensitiveData = { password: 'secret123', apiKey: 'key-456' };
db.insert('secrets', {
    id: 1,
    data: encrypt(sensitiveData, 'my-key'),
    type: 'credentials'
});

// Decrypt when retrieving
const record = db.where('id', 1).getOne('secrets');
const decryptedData = decrypt(record.data, 'my-key');

🌟 Real-World Examples

E-commerce Product Catalog

const db = new RockdexDB({ storageMode: 'memory' });

// Create products table with schema
const productSchema = {
    name: { type: 'string', required: true },
    price: { type: 'number', required: true, min: 0 },
    category: { type: 'string', required: true },
    inStock: { type: 'boolean', required: false }
};

db.createTable('products', productSchema);

// Add sample products
db.bulkInsert('products', [
    { name: 'Laptop Pro', price: 1299, category: 'Electronics', inStock: true },
    { name: 'Coffee Mug', price: 15, category: 'Kitchen', inStock: true },
    { name: 'Running Shoes', price: 89, category: 'Sports', inStock: false }
]);

// Find affordable products in stock
const affordableProducts = db
    .whereOperator('price', '<', 100)
    .where('inStock', true)
    .orderBy('price', 'ASC')
    .get('products');

User Management with Sessions

const db = new RockdexDB({ 
    storageMode: 'file',
    storagePath: './userdata',
    storageTable: ['users.rdb', 'sessions.rdb'],
    timestamps: true
});

await db.ready();

// Create tables
db.createTable('users');
db.createTable('sessions');

// Add trigger for automatic session creation
db.createTrigger('users', 'afterInsert', ({ NEW }) => {
    db.insert('sessions', {
        userId: NEW.id,
        token: 'session_' + Math.random().toString(36),
        expiresAt: Date.now() + (24 * 60 * 60 * 1000) // 24 hours
    });
    return true;
});

// Register new user (automatically creates session)
db.insert('users', {
    username: 'john_doe',
    email: '[email protected]',
    role: 'user'
});
