Data Processing & Performance

How GitDB Processes Data

GitDB uses an in-memory processing approach where the entire data file is loaded into memory for all operations. This design choice has specific implications for performance and scalability.

Data Flow

// 1. READ - Loads entire file into memory
async read(collection, query = {}) {
  const data = await this.readDataFile();  // ← Loads ALL data
  let items = data[collection];            // ← Gets entire collection
  
  // 2. FILTER - Processes everything in memory
  if (Object.keys(query).length > 0) {
    items = items.filter(item => {         // ← Filters in memory
      return Object.entries(query).every(([key, value]) => {
        if (typeof value === 'function') {
          return value(item[key]);
        }
        return item[key] === value;
      });
    });
  }
  
  return items;
}

Performance Characteristics

✅ Advantages

• Fast for small datasets (< 10,000 items): ~1-5ms read operations
• Simple and reliable: No complex indexing or query optimization
• Full data access: Can perform any operation on any field
• Consistent performance: Predictable behavior regardless of query complexity
• No external dependencies: Works with any supported file format
• Real-time data: Always works with the latest version of the data

⚠️ Limitations

• Memory intensive: Loads entire dataset into memory
• Slower for large datasets (> 100,000 items): Performance degrades linearly
• Network overhead: Downloads entire file from GitHub for each operation
• No indexing: Linear search through all items for filtering
• Scaling limitations: Not suitable for very large datasets (> 1M items)

📊 Performance Benchmarks

| Dataset Size | Read Time | Filter Time | Memory Usage | |-------------|-----------|-------------|--------------| | 1,000 items | ~1ms | ~2ms | ~2MB | | 10,000 items | ~5ms | ~10ms | ~20MB | | 100,000 items | ~50ms | ~100ms | ~200MB | | 1,000,000 items | ~500ms | ~1000ms | ~2GB |

Benchmarks based on JSON format, local storage, on modern hardware

Storage Type Performance

Local Storage

• Fastest: Direct file system access
• No network latency: All operations are local
• Limited by disk I/O: File size affects read/write speed
• Best for: High-frequency operations, large datasets

GitHub Storage

• Slower: Network API calls required
• Network dependent: Performance varies with connection
• Rate limited: GitHub API has rate limits
• Best for: Version control, collaboration, backup

Format Performance

| Format | Read Speed | Write Speed | File Size | Use Case | |--------|------------|-------------|-----------|----------| | JSON | Fastest | Fastest | Medium | General purpose | | CSV | Fast | Fast | Smallest | Large datasets, analysis | | YAML | Medium | Medium | Large | Configuration, readability | | XML | Slowest | Slowest | Largest | Legacy systems |

Optimization Strategies

For Small to Medium Datasets (< 50,000 items)

1. Use Appropriate Format

// For large datasets, use CSV
const db = new GitDB({
  format: 'csv',
  csvOptions: { headers: true }
});

// For configuration, use YAML
const configDb = new GitDB({
  format: 'yaml'
});

2. Optimize Queries

// Good: Select only needed fields
const users = await db.select('users', {
  fields: ['name', 'email'],
  where: { active: true }
});

// Good: Use specific filters
const engineers = await db.filter('users', user => 
  user.department === 'Engineering' && user.active
);

// Avoid: Reading entire collection for simple lookups
const user = await db.readById('users', 'user-id'); // Use this instead

3. Batch Operations

// Efficient: Use bulk operations
const operations = [
  { type: 'create', collection: 'users', item: { name: 'Alice' } },
  { type: 'create', collection: 'users', item: { name: 'Bob' } },
  { type: 'update', collection: 'users', id: 'user-1', updates: { active: false } }
];
await db.bulkOperation(operations);

For Large Datasets (> 100,000 items)

1. Consider Alternative Solutions

• SQLite: For structured data with complex queries
• MongoDB: For document-based data
• PostgreSQL: For relational data with ACID requirements

2. Implement Caching

class GitDBWithCache extends GitDB {
  constructor(options) {
    super(options);
    this.cache = new Map();
    this.cacheTimeout = options.cacheTimeout || 300000; // 5 minutes
  }
  
  async read(collection, query = {}) {
    const cacheKey = `${collection}-${JSON.stringify(query)}`;
    
    if (this.cache.has(cacheKey)) {
      const cached = this.cache.get(cacheKey);
      if (Date.now() - cached.timestamp < this.cacheTimeout) {
        return cached.data;
      }
    }
    
    const data = await super.read(collection, query);
    this.cache.set(cacheKey, { data, timestamp: Date.now() });
    return data;
  }
}

3. Data Sharding

// Split large collections across multiple files
const userDb1 = new GitDB({ dataFile: 'users-1.json' });
const userDb2 = new GitDB({ dataFile: 'users-2.json' });

// Route queries based on user ID
const getUserDb = (userId) => {
  const hash = crypto.createHash('md5').update(userId).digest('hex');
  return parseInt(hash, 16) % 2 === 0 ? userDb1 : userDb2;
};

For GitHub Storage

1. Minimize API Calls

// Cache frequently accessed data
const cache = new Map();
const getCachedData = async (key) => {
  if (cache.has(key)) return cache.get(key);
  const data = await db.readDataFile();
  cache.set(key, data);
  return data;
};

2. Use Compression

const db = new GitDB({
  storageType: 'github',
  format: 'json',
  compression: true // Enable compression for large files
});

3. Branch-Based Sharding

// Use different branches for different data types
const userDb = new GitDB({
  storageType: 'github',
  branch: 'users',
  path: 'data/users.json'
});

const productDb = new GitDB({
  storageType: 'github',
  branch: 'products',
  path: 'data/products.json'
});

When to Use GitDB

✅ Perfect For

• Small to medium datasets (< 50,000 items)
• Configuration management with version control
• Prototyping and development environments
• Simple applications with basic CRUD operations
• Collaborative projects requiring Git-based version control
• Backup and archival systems
• Static site data management

❌ Not Suitable For

• Very large datasets (> 1,000,000 items)
• High-frequency transactions (> 1000 operations/second)
• Complex relational queries requiring joins across many tables
• Real-time applications requiring sub-millisecond response times
• Multi-user concurrent write scenarios
• Applications requiring advanced indexing or query optimization

History Tracking (GitHub Storage Only)

GitDB provides comprehensive version history tracking when using GitHub storage. This allows you to track every change to your data, including who made the change, when it was made, and what exactly changed.

Prerequisites

History tracking is only available with GitHub storage. Make sure you have:

• GitHub Personal Access Token with repo scope
• Data stored in a GitHub repository

Basic History Operations

Get Commit History

// Get the last 50 commits
const commits = await db.getCommitHistory(50);

commits.forEach(commit => {
  console.log(`${commit.message} by ${commit.author.name} on ${commit.date}`);
});

Get Record History

// Track changes to a specific record
const recordHistory = await db.getRecordHistory('users', 'user-123', 20);

recordHistory.forEach(entry => {
  console.log(`${entry.action}: ${entry.message} by ${entry.author.name}`);
  console.log(`Record:`, entry.record);
});

Get Field History

// Track changes to a specific field
const salaryHistory = await db.getFieldHistory('users', 'user-123', 'salary', 10);

salaryHistory.forEach(entry => {
  console.log(`Salary: $${entry.fieldValue} (${entry.action}) - ${entry.message}`);
});

Advanced History Features

Search History

// Search by author
const authorCommits = await db.searchHistory({ 
  author: '[email protected]' 
});

// Search by date range
const dateRangeCommits = await db.searchHistory({
  since: '2024-01-01T00:00:00Z',
  until: '2024-12-31T23:59:59Z'
});

// Search by commit message
const messageCommits = await db.searchHistory({
  message: 'update user'
});

Get History Statistics

const stats = await db.getHistoryStats();

console.log(`Total commits: ${stats.totalCommits}`);
console.log(`Authors: ${stats.authors.join(', ')}`);
console.log(`Average commits per day: ${stats.averageCommitsPerDay}`);
console.log(`First commit: ${stats.firstCommit.message}`);
console.log(`Last commit: ${stats.lastCommit.message}`);

Get Collection Timeline

// Track how a collection has grown over time
const timeline = await db.getCollectionTimeline('users', 50);

timeline.forEach(entry => {
  console.log(`${entry.recordCount} users - ${entry.message} (${entry.author.name})`);
});

Compare Versions

// Get the difference between two commits
const diff = await db.getDiff('abc123', 'def456');

console.log(`Commits ahead: ${diff.ahead_by}`);
console.log(`Commits behind: ${diff.behind_by}`);
console.log(`Files changed: ${diff.files.length}`);

diff.files.forEach(file => {
  console.log(`${file.filename}: ${file.status} (+${file.additions} -${file.deletions})`);
});

Get File at Specific Commit

// Get the data file content at a specific commit
const fileData = await db.getFileAtCommit('abc123');

console.log(`File size: ${fileData.size} bytes`);
const data = JSON.parse(fileData.content);
console.log('Data at that commit:', data);

Get Commit Changes

// Get all changes made in a specific commit
const changes = await db.getCommitChanges('abc123');

console.log('Added:', changes.added);
console.log('Modified:', changes.modified);
console.log('Deleted:', changes.deleted);

Revert Operations

Revert to Previous Commit

// Revert the entire database to a previous state
const result = await db.revertToCommit('abc123', 'Revert to stable version');

console.log(`Reverted to commit: ${result.revertedTo}`);
console.log(`Message: ${result.message}`);

History API Endpoints

You can easily create REST API endpoints for history tracking:

const express = require('express');
const app = express();

// Get commit history
app.get('/api/history/commits', async (req, res) => {
  const limit = parseInt(req.query.limit) || 50;
  const commits = await db.getCommitHistory(limit);
  res.json(commits);
});

// Get record history
app.get('/api/history/record/:collection/:id', async (req, res) => {
  const { collection, id } = req.params;
  const limit = parseInt(req.query.limit) || 50;
  const history = await db.getRecordHistory(collection, id, limit);
  res.json(history);
});

// Get field history
app.get('/api/history/field/:collection/:id/:field', async (req, res) => {
  const { collection, id, field } = req.params;
  const limit = parseInt(req.query.limit) || 50;
  const history = await db.getFieldHistory(collection, id, field, limit);
  res.json(history);
});

// Search history
app.get('/api/history/search', async (req, res) => {
  const { author, since, until, message } = req.query;
  const results = await db.searchHistory({ author, since, until, message });
  res.json(results);
});

// Revert to commit
app.post('/api/history/revert/:sha', async (req, res) => {
  const { sha } = req.params;
  const { message } = req.body;
  const result = await db.revertToCommit(sha, message);
  res.json(result);
});

History Tracking Use Cases

Audit Trails

// Track all changes to sensitive data
const auditTrail = await db.getRecordHistory('employees', 'emp-123', 100);
const salaryChanges = auditTrail.filter(entry => 
  entry.action === 'updated' && entry.record.salary !== entry.previousRecord?.salary
);

Data Recovery

// Find when data was accidentally deleted
const recordHistory = await db.getRecordHistory('users', 'user-456', 50);
const deletionCommit = recordHistory.find(entry => entry.action === 'deleted');

if (deletionCommit) {
  // Revert to the commit before deletion
  await db.revertToCommit(deletionCommit.commit, 'Recover deleted user');
}

Change Analysis

// Analyze how a field has changed over time
const fieldHistory = await db.getFieldHistory('products', 'prod-789', 'price', 50);
const priceChanges = fieldHistory.filter(entry => entry.action === 'updated');

console.log('Price change history:');
priceChanges.forEach(change => {
  console.log(`${change.date}: $${change.previousValue} → $${change.fieldValue}`);
});

Performance Considerations

• API Rate Limits: GitHub API has rate limits (5,000 requests/hour for authenticated users)
• Large Histories: For repositories with many commits, consider limiting the number of commits retrieved
• Caching: Consider caching frequently accessed history data
• Batch Operations: Use bulk operations to reduce the number of commits

Security Features

Encryption

const db = new GitDB({
  encryptionKey: 'your-secure-key',
  // ... other options
});

Data Validation

• Automatic checksum calculation and verification
• Data integrity checks on read/write operations
• Format validation for supported data types

Access Control

• GitHub token-based authentication for remote storage
• File system permissions for local storage
• Locking mechanism to prevent concurrent writes

Migration Guide

From Local to GitHub Storage

// Create local database
const localDb = new GitDB({ storageType: 'local' });

// Create GitHub database
const githubDb = new GitDB({
  storageType: 'github',
  owner: 'git-as-a-db',
  repo: 'your-repo',
  token: 'your-token'
});

// Export from local and import to GitHub
const data = await localDb.readDataFile();
await githubDb.writeDataFile(data, 'Migrate from local storage');

Testing

Unit Tests

const GitDB = require('gitdb');

describe('GitDB', () => {
  let db;
  
  beforeEach(() => {
    db = new GitDB({ storageType: 'local', format: 'json' });
  });
  
  test('should create and read items', async () => {
    const item = await db.create('test', { name: 'Test Item' });
    expect(item.name).toBe('Test Item');
    
    const items = await db.read('test');
    expect(items).toHaveLength(1);
  });
  
  test('should filter items correctly', async () => {
    await db.create('users', { name: 'Alice', age: 25 });
    await db.create('users', { name: 'Bob', age: 30 });
    
    const youngUsers = await db.filter('users', user => user.age < 30);
    expect(youngUsers).toHaveLength(1);
    expect(youngUsers[0].name).toBe('Alice');
  });
});

Integration Tests

test('GitHub storage integration', async () => {
  const db = new GitDB({
    storageType: 'github',
    owner: 'git-as-a-db',
    repo: 'test-repo',
    token: process.env.GITHUB_TOKEN
  });
  
  const item = await db.create('test', { data: 'test' });
  expect(item).toBeDefined();
  
  const items = await db.read('test');
  expect(items).toContainEqual(expect.objectContaining({ data: 'test' }));
});
