What are the differences between async SQLAlchemy and synchronous SQLAlchemy?

What are the differences between async SQLAlchemy and synchronous SQLAlchemy?

Async SQLAlchemy allows for non-blocking database operations, making it suitable for high-concurrency applications, while synchronous SQLAlchemy blocks the execution until the database operation completes.

When should I use async SQLAlchemy?

You should use async SQLAlchemy when building applications that require handling many simultaneous connections, like web servers or APIs.

Are there any performance benefits to using async?

Yes, async can improve performance in I/O-bound applications by allowing other tasks to run while waiting for database responses.

What are the downsides of using async SQLAlchemy?

The downsides include increased complexity in code and the need for an async-compatible environment, which may not be necessary for simpler applications.
