Implementation Status

Implemented Features

Q: Is QuantaDB compatible with pure Dart projects?
A: Yes! While QuantaDB uses Flutter's path_provider for secure storage locations, it's fully compatible with pure Dart projects. The Flutter dependency is optional and can be removed for server-side use.

Q: Do the performance benchmarks include disk I/O operations?
A: Yes, all benchmark statistics include disk I/O operations, including MemTable flushes and SSTable compactions. This gives you a realistic picture of real-world performance.

Q: Does QuantaDB support multi-isolate operations?
A: Yes! QuantaDB is designed with multi-isolate support, featuring:

  • Thread-safe architecture with proper synchronization
  • Isolate workers for background operations
  • Proper locking mechanisms
  • Transaction isolation levels
  • Background workers for compaction and query processing

Q: What query capabilities are currently available?
A: The current query system supports:

  • Predicates (filtering)
  • Sorting
  • Pagination
  • Basic aggregations
  • Type-safe query interface

Q: Does QuantaDB support transactions?
A: Yes! QuantaDB implements ACID-compliant transactions with:

  • Atomic operations
  • Commit and rollback functionality
  • Proper isolation levels
  • Error handling and recovery
