How can I use asyncio with databases in Python?

You can use the asyncio library along with an async database driver like aiomysql or asyncpg to perform non-blocking database operations.

Can you show me a simple example of using asyncpg?

Sure! Here's a basic example:

import asyncio
import asyncpg

async def fetch_data():
    conn = await asyncpg.connect(user='user', password='password', database='db', host='127.0.0.1')
    rows = await conn.fetch('SELECT * FROM my_table')
    await conn.close()
    return rows

loop = asyncio.get_event_loop()
result = loop.run_until_complete(fetch_data())
print(result)

What are the benefits of using asyncio with databases?

Using asyncio allows for concurrent database operations, improving performance and responsiveness in applications, especially under high load.

Are there any limitations I should be aware of?

Yes, not all database drivers support asyncio, and you may encounter issues with connection pooling and transaction management.
