Have you used asynchronous functions in FastAPI frameworks?

In FastAPI, asynchronous functions are used to handle requests, allowing efficient handling of I/O operations without blocking the main thread. For example, you can define an endpoint with async def that performs an asynchronous request to a database or external API:

from fastapi import FastAPI
import httpx

app = FastAPI()

@app.get("/async-example")
async def async_example():
    async with httpx.AsyncClient() as client:
        response = await client.get('https://example.com')
    return {"status_code": response.status_code}

This approach enables handling multiple requests simultaneously, increasing the application's performance.
