How can I perform bulk operations in SQLAlchemy?

How can I perform bulk operations in SQLAlchemy?

You can use methods like bulk_insert_mappings, bulk_save_objects, or execute with raw SQL for bulk operations.

What are the differences between bulk_insert_mappings and bulk_save_objects?

bulk_insert_mappings is faster for inserting multiple rows as it bypasses some ORM features, while bulk_save_objects retains ORM features but is slower.

Can I use bulk operations with relationships in SQLAlchemy?

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

Are there any performance considerations I should be aware of?

Yes, bulk operations can significantly improve performance, but be cautious with memory usage and transaction sizes.
