What are the best practices for bulk inserting data in Django?

When bulk inserting data in Django, it's important to use the bulk_create method for efficiency. You should also consider using transactions to ensure data integrity.

Are there any limitations I should be aware of when using bulk_create?

Yes, bulk_create does not call the save() method on each instance, so signals like pre_save and post_save won't be triggered. Also, it may not handle unique constraints well.

How can I handle unique constraints during bulk inserts?

To handle unique constraints, you can catch the IntegrityError exception and decide how to manage duplicates, or you can preprocess your data to ensure uniqueness before the insert.

Is there a way to update existing records during a bulk insert?

Django's bulk_create does not support updates. You would need to use a combination of bulk_create for new records and update for existing ones.
