How can I integrate an asynchronous database with Flask?

You can use libraries like SQLAlchemy with async support or databases like asyncpg for PostgreSQL. Would you like a code example?

Yes, please provide a code example for using asyncpg with Flask.

Sure! First, install asyncpg and Flask. Then, you can set up your Flask app like this:

from flask import Flask
import asyncpg

app = Flask(__name__)

async def get_db_connection():
    return await asyncpg.connect(user='user', password='password', database='dbname', host='127.0.0.1')

@app.route('/data')
async def get_data():
    conn = await get_db_connection()
    rows = await conn.fetch('SELECT * FROM my_table')
    await conn.close()
    return {'data': [dict(row) for row in rows]}

What are the benefits of using async databases with Flask?

Using async databases can improve performance by allowing your app to handle multiple requests concurrently, reducing latency.
