Async SQLAlchemy vs Sync SQLAlchemy: Which One to Choose?

What are the main differences between async SQLAlchemy and sync SQLAlchemy?

Async SQLAlchemy allows for non-blocking database operations, making it suitable for high-concurrency applications, while sync SQLAlchemy is blocking and simpler to use for traditional applications.

When should I use async SQLAlchemy over sync?

You should consider using async SQLAlchemy if your application needs to handle many simultaneous connections or if you're building an I/O-bound application.

Are there any performance benefits to using async SQLAlchemy?

Yes, async SQLAlchemy can improve performance in scenarios with high I/O operations, as it allows other tasks to run while waiting for database responses.

Can I mix async and sync SQLAlchemy in the same project?

It's generally not recommended to mix them in the same project due to potential complications in managing the event loop and database sessions.

What are some common pitfalls when using async SQLAlchemy?

Common pitfalls include not properly managing the event loop, forgetting to await async calls, and potential issues with session management.
