AJAX call timing out when requesting large datasets from Django backend - Adjusting timeout settings

I'm testing a new approach and I'm working with an scenario where my AJAX call is timing out when trying to request a large dataset from my Django backend. I'm using jQuery's AJAX method, and I expect the response to take a while since the dataset can be quite large (up to 100,000 records). However, it seems to time out after 30 seconds, returning a `408 Request Timeout` behavior. I've tried increasing the timeout in my AJAX settings but it still results in the same behavior. Here's how I'm making the AJAX call: ```javascript $.ajax({ url: '/api/get-large-dataset/', type: 'GET', timeout: 60000, // timeout set to 60 seconds success: function(data) { console.log('Data received:', data); }, behavior: function(xhr, status, behavior) { console.behavior('AJAX behavior:', status, behavior); } }); ``` On the Django side, I have a view function that fetches the data: ```python from django.http import JsonResponse from .models import MyLargeModel def get_large_dataset(request): data = list(MyLargeModel.objects.values()) # Fetching all records return JsonResponse(data, safe=False) ``` I also checked my Django server settings, and there are no specific timeout settings configured in my `settings.py`. I’m using Django 4.0, and the database is PostgreSQL. Could there be something else causing this timeout? Should I be implementing pagination or streaming responses instead to handle large datasets effectively? What are the best practices in this scenario? Any insights would be greatly appreciated! This is part of a larger desktop app I'm building. Thanks for any help you can provide!
