I'm excited to announce the beta release of QuantaDB, a high-performance NoSQL local database built entirely in Dart. After months of development and testing, we're ready to share this powerful database solution with the Dart and Flutter community.

Why QuantaDB?​

As a Flutter developer, I've often encountered limitations with existing local database solutions. Many options either had external dependencies, performance bottlenecks, or lacked modern features. This led me to create QuantaDB, a database that addresses these challenges while providing a developer-friendly experience.

Key Features​

🚀 High Performance​

QuantaDB implements a Log-Structured Merge Tree (LSM-Tree) storage engine from scratch in pure Dart. Our benchmarks show impressive results:

• 10,000 write operations in just 30ms
• 10,000 read operations in 9ms
• Batch operations (1000 items) completed in 15ms

🔒 Data Security​

Security is a top priority:

• Built-in field-level encryption
• Platform-specific secure storage
• Access control lists
• Runtime and compile-time validation

📊 Advanced Features​

• Real-time updates with reactive queries
• Type safety with code generation
• Cross-platform compatibility
• Powerful query engine with filtering and sorting
• ACID compliant transactions
• Efficient handling of large datasets

Architecture​

QuantaDB is built with a layered architecture:

1. Application Layer: Public API and code generation integration
2. Core Engine Layer: Query processing and storage management
3. Storage Layer: LSM-Tree implementation with MemTable and SSTables
4. Platform Layer: File system interaction and background tasks

Getting Started​

Adding QuantaDB to your project is straightforward:

dependencies:
  quanta_db: ^0.0.5

Basic usage example:

import 'package:quanta_db/quanta_db.dart';

void main() async {
  final db = await QuantaDB.open('my_database');

  // Store data
  await db.put('user:1', {
    'name': 'John Doe',
    'email': 'john@example.com'
  });

  // Retrieve data
  final user = await db.get('user:1');
  print('User: $user');

  await db.close();
}
