What are the differences between asyncpg and SQLAlchemy?

Asyncpg is a database interface library for PostgreSQL that supports asynchronous programming, while SQLAlchemy is an ORM that provides a high-level abstraction for database interactions. Asyncpg is generally faster for raw queries, while SQLAlchemy offers more features for complex data models.

Which one should I use for a new project?

It depends on your project's requirements. If you need high performance and are comfortable with raw SQL, asyncpg might be better. If you prefer an ORM for easier data manipulation and relationships, go with SQLAlchemy.

Can I use them together?

Yes, you can use asyncpg for raw queries and SQLAlchemy for ORM features. Just ensure that your database session management is compatible with async programming.

What are some performance considerations?

Asyncpg generally offers better performance for raw queries due to its lightweight nature. SQLAlchemy can introduce some overhead, but it provides optimizations for complex queries and relationships.
