How can I use Flask-SQLAlchemy for asynchronous queries?

You can use Flask-SQLAlchemy with async capabilities by integrating it with an async framework like FastAPI or using async libraries.

What libraries do I need to install for async support?

You will need to install asyncpg for PostgreSQL or aiomysql for MySQL, along with Flask-SQLAlchemy.

Can you show me a code example?

Sure! Here's a simple example:

from flask import Flask
from flask_sqlalchemy import SQLAlchemy

app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'postgresql+asyncpg://user:password@localhost/dbname'
db = SQLAlchemy(app)

async def get_users():
    async with db.session() as session:
        result = await session.execute(select(User))
        return result.scalars().all()

What are the benefits of using async queries?

Async queries can improve performance by allowing your application to handle other tasks while waiting for database responses.
