What are the different transaction isolation levels in Django ORM?

In Django ORM, the transaction isolation levels are defined by the underlying database. Common levels include READ UNCOMMITTED, READ COMMITTED, REPEATABLE READ, and SERIALIZABLE.

Can you explain what each isolation level means?

Sure!

• READ UNCOMMITTED: Allows dirty reads, meaning one transaction can see uncommitted changes made by another.
• READ COMMITTED: Prevents dirty reads; a transaction can only see committed changes.
• REPEATABLE READ: Ensures that if a row is read twice in the same transaction, it will return the same data, preventing non-repeatable reads.
• SERIALIZABLE: The strictest level, it ensures complete isolation from other transactions, simulating serial execution.

Which isolation level is the default in Django?

The default isolation level in Django is READ COMMITTED, which balances performance and data integrity.

How can I change the isolation level in my Django project?

You can change the isolation level by using the transaction.set_autocommit() method or by configuring it in your database settings, depending on the database backend you are using.
