advanced Published 29 Jun 2026
Action Steps
  1. Build a Python ORM using Tortoise ORM as a reference
  2. Use PyO3 to create a Rust engine for the ORM
  3. Configure asyncio to handle asynchronous database queries
  4. Apply the GIL limitation workaround using Rust and PyO3
  5. Test the performance of the ORM with the Rust engine
