QuantaDB Roadmap: Building the Future of Dart Databases

Today, I'm excited to share our detailed roadmap for QuantaDB, highlighting what we've accomplished and what's coming next. This roadmap reflects our commitment to building a high-performance, developer-friendly database solution for the Dart and Flutter ecosystem.

What We've Built So Far 🏗️

Phase 1: Core Storage Engine ✅

We've successfully implemented the foundation of QuantaDB with a pure Dart LSM-Tree storage engine. Here's what's already working:

• High-Performance Storage

  • MemTable using SplayTreeMap for O(log n) writes
  • SSTable serialization with 4KB block alignment
  • Three-layer Bloom filters for lightning-fast lookups
  • Background compaction using Isolate workers

• Robust Data Management

  • Transaction support with atomic operations
  • Type-safe change notifications
  • Efficient binary serialization with DartBson
  • Comprehensive error handling and recovery

Phase 2: Code Generation (In Progress) 🔄

We're currently working on making QuantaDB more developer-friendly through annotation-driven code generation:

• Completed Features

  • @QuantaEntity annotation system
  • Primary key and index support
  • Field validation with constraints
  • Schema version tracking
  • Basic composite indexes

• Currently Working On

  • Type adapter generation
  • DAO class generation
  • Enhanced schema validation
  • Advanced index management

What's Coming Next 🚀

Phase 2 Completion (Q2 2024)

We're focusing on completing these critical features:

• Relationship Management

  • Entity relationships
  • Referential integrity
  • Efficient relationship querying

• Advanced Validation

  • Custom validation functions
  • Compile-time validation
  • Runtime data quality checks

Phase 3: Reactive Query System (Q3 2024)

Our next major phase will bring real-time capabilities:

• Stream-Based Watching

  • Real-time query updates
  • Efficient change detection
  • Query result caching
  • Incremental updates

• Change Notification Pipeline

  • Object hashing system
  • Batched updates
  • Isolate-based propagation
  • Memory-efficient diffing

Performance Goals 🎯

We're committed to maintaining high performance while adding new features:

Operation	Target (100k ops)	Current Status
Bulk Insert	820ms	✅ Achieved
Point Query	0.8μs	✅ Achieved
Range Query	4.2ms	✅ Achieved
Encrypted Write	1.9ms/op	🔄 In Progress
Change Propagation	12ms latency	⏳ Planned
