How does transaction management work in Django's async ORM?

In Django's async ORM, transaction management allows you to group multiple database operations into a single unit. This ensures that either all operations succeed or none do, maintaining data integrity.

Can you give me an example of how to use it?

Sure! You can use the database.transaction() context manager to wrap your database operations. Here's a simple example:

from django.db import transaction

async def my_view(request):
    async with transaction.atomic():
        await MyModel.objects.create(field='value')
        await AnotherModel.objects.create(field='value')

This ensures both operations are committed together.

What happens if one of the operations fails?

If one of the operations fails within the transaction.atomic() block, all changes made in that block will be rolled back, ensuring that your database remains consistent.

Are there any performance considerations I should be aware of?

Yes, using transactions can introduce some overhead, especially if you have long-running transactions. It's best to keep transactions as short as possible to minimize locking and improve performance.
