Django: Bulk Create vs Save

What's the difference between bulk_create and save in Django?

Bulk create allows you to insert multiple records into the database in a single query, while save is used for individual record updates.

When should I use bulk_create?

Use bulk_create when you need to insert a large number of records efficiently, as it reduces the number of database hits.

Are there any limitations to bulk_create?

Yes, bulk_create doesn't call the save method on each instance, so signals like pre_save and post_save won't be triggered.

Can I use bulk_create with related objects?

You can, but you need to ensure that the related objects are already saved in the database, as bulk_create won't handle relationships.
