Django asyncio httpx database Python

I've searched everywhere and can't find a clear answer. I'm working on a Django application (version 3.2) where I need to implement an asynchronous view that performs both a database query and an external API call using the `httpx` library. However, I'm working with issues with timeouts when calling the external API, which causes the entire request to hang. I suspect that my database query is blocking the event loop. Here's a simplified version of my view: ```python from django.http import JsonResponse from django.views.decorators.csrf import csrf_exempt import httpx from asgiref.sync import sync_to_async from .models import MyModel @csrf_exempt async def my_async_view(request): if request.method == 'GET': data = await get_database_data() api_response = await fetch_external_api() return JsonResponse({'data': data, 'api_response': api_response}) async def get_database_data(): return await sync_to_async(MyModel.objects.all)() async def fetch_external_api(): async with httpx.AsyncClient() as client: response = await client.get('https://api.example.com/data', timeout=5.0) return response.json() ``` I've implemented the function `get_database_data` to run the database query in a separate thread using `sync_to_async`, but I still occasionally get a `TimeoutError` when the external API call takes too long. Additionally, I noticed that if the external API is down, my whole view becomes unresponsive. I tried increasing the timeout value in the `httpx` call, but that doesn't seem to help if the database query takes longer than expected. Should I run the database query in a separate thread or process entirely, or is there a better way to handle these concurrent tasks? Any suggestions on how to improve the responsiveness and avoid these timeout issues would be highly appreciated! I'm working with Python in a Docker container on Windows 10. Any suggestions would be helpful. The project is a web app built with Python. Hoping someone can shed some light on this.
