What are the limitations of bulk inserts in Django?

What are the limitations of bulk inserts in Django?

Bulk inserts in Django can be very efficient, but they have some limitations. For instance, they don't support certain features like signals, and you can't use them with model methods that rely on the instance being saved.

Can you explain why signals are not supported?

Sure! Signals in Django are designed to respond to model events like saving or deleting an instance. Since bulk inserts bypass the individual save method, signals won't be triggered for those instances.

Are there any performance issues I should be aware of?

Yes, while bulk inserts are generally faster, if you're inserting a very large number of records, you might hit database limits or experience memory issues. It's important to batch your inserts.

What is the maximum number of records I can insert at once?

The maximum number of records you can insert at once depends on your database backend. For example, PostgreSQL has a limit of 65,535 parameters in a single query, which can affect your bulk insert size.
