How can I perform asynchronous operations with SQLAlchemy?

You can use SQLAlchemy's async API by utilizing the asyncio library along with the async and await keywords.

Can you show me a simple example of using async with SQLAlchemy?

Sure! Here's a basic example:

import asyncio
from sqlalchemy.ext.asyncio import create_async_engine, AsyncSession
from sqlalchemy.orm import sessionmaker

engine = create_async_engine('postgresql+asyncpg://user:password@localhost/dbname')
AsyncSessionLocal = sessionmaker(bind=engine, class_=AsyncSession, expire_on_commit=False)

async def get_data():
    async with AsyncSessionLocal() as session:
        result = await session.execute('SELECT * FROM my_table')
        return result.scalars().all()

asyncio.run(get_data())

What are the benefits of using async operations in SQLAlchemy?

Using async operations can improve performance by allowing your application to handle multiple database requests concurrently, reducing wait times.

Are there any limitations I should be aware of when using async with SQLAlchemy?

Yes, some limitations include the need for an async-compatible database driver and potential complexity in managing async sessions.
