What are the different transaction isolation levels in Django?

Django supports several transaction isolation levels, including READ UNCOMMITTED, READ COMMITTED, REPEATABLE READ, and SERIALIZABLE. Each level controls how transactions interact with each other.

Can you explain what each isolation level means?

Sure!

• READ UNCOMMITTED: Allows dirty reads, meaning one transaction can see uncommitted changes from another.
• READ COMMITTED: Prevents dirty reads, but non-repeatable reads can occur.
• REPEATABLE READ: Ensures that if a row is read twice in the same transaction, it will return the same data, but phantom reads can happen.
• SERIALIZABLE: The strictest level, it prevents dirty reads, non-repeatable reads, and phantom reads by ensuring complete isolation.

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 setting the isolation_level parameter in your database connection settings in Django's settings.py file.
