Using asynchronous path operations

When it comes to improving performance, FastAPI is an asynchronous framework, and it uses Python’s AsyncIO principles and concepts to create a REST API implementation that can run separately and independently from the application’s main thread. The idea also applies to how a background task is executed. Now, to create an asynchronous REST endpoint, attach async to the func signature of the service:

@router.get("/feedback/list")
async def show_tourist_post(touristId: UUID):
    tourist_posts = [assess for assess in feedback_tour.values() 
            if assess.tourist_id == touristId]
    tourist_posts_json = jsonable_encoder(tourist_posts) 
    return JSONResponse(content=tourist_posts_json,
                   status_code...
