How can I use Flask with asynchronous database operations?

Can you explain how to use Flask with asynchronous database operations?

Sure! Flask can be used with async database operations by integrating libraries like SQLAlchemy with async support.

What are some examples of async database operations in Flask?

You can perform operations like async queries, inserts, and updates using async functions in your Flask routes.

Are there any specific libraries I should use for async support?

Yes, you can use libraries like asyncpg for PostgreSQL or aiomysql for MySQL along with SQLAlchemy.

Can you provide a code snippet for an async query?

Certainly! Here's a simple example:

from flask import Flask
from sqlalchemy.ext.asyncio import AsyncSession, create_async_engine

app = Flask(__name__)
engine = create_async_engine('postgresql+asyncpg://user:password@localhost/dbname')

@app.route('/async-query')
async def async_query():
    async with AsyncSession(engine) as session:
        result = await session.execute('SELECT * FROM my_table')
        return result.fetchall()
