An example of an AI chatbot conversation about optimizing SQLAlchemy queries for performance.
How can I optimize my SQLAlchemy queries for better performance?
To optimize SQLAlchemy queries, consider using eager loading, indexing your database, and filtering results early.
What is eager loading and how does it help?
Eager loading retrieves related objects in a single query, reducing the number of database hits and improving performance.
Are there specific indexing strategies I should follow?
Yes, index columns that are frequently used in WHERE clauses, JOINs, and ORDER BY statements to speed up query execution.
Can you give an example of a query that uses eager loading?
Sure! You can use session.query(Parent).options(joinedload(Parent.children)).all() to eagerly load children with parents.
