How can I optimize my Flask application using ORM?
To optimize your Flask application with ORM, consider using techniques like eager loading, indexing, and query optimization.
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.
Can you give me an example of how to implement eager loading?
Sure! In SQLAlchemy, you can use the joinedload
option when querying to load related objects eagerly.
Are there any other performance tips for using SQLAlchemy with Flask?
Yes, you can also use connection pooling, avoid N+1 queries, and profile your queries to identify bottlenecks.
