How can I perform batch operations in SQLAlchemy?

How can I perform batch operations in SQLAlchemy?

You can use the session.bulk_insert_mappings() or session.bulk_save_objects() methods for batch operations.

What are the differences between bulk_insert_mappings and bulk_save_objects?

bulk_insert_mappings is used for inserting multiple rows with dictionaries, while bulk_save_objects is for ORM objects.

Are there any performance benefits to using these methods?

Yes, both methods are optimized for performance and can significantly reduce the number of database round trips.

Can I use these methods with relationships?

Yes, but you need to handle relationships manually when using bulk operations, as they don't automatically manage them.
