Django: When to Use Async vs Sync?

What are the main differences between async and sync in Django?

In Django, sync (synchronous) code runs in a single thread, blocking other requests until it's done, while async (asynchronous) code can handle multiple requests concurrently, improving performance for I/O-bound tasks.

Can you give me examples of when to use async over sync?

Sure! Use async for tasks like handling WebSocket connections or making multiple API calls simultaneously. Sync is better for CPU-bound tasks or when working with legacy code.

Are there any downsides to using async in Django?

Yes, async can add complexity to your code and may not be necessary for all applications. It also requires an understanding of async programming patterns.

How can I convert my existing sync views to async?

You can convert sync views to async by using the async def syntax and ensuring that any I/O operations are also async, like using httpx for HTTP requests.
