How can I optimize relationships in SQLAlchemy?

To optimize relationships in SQLAlchemy, consider using lazy loading, eager loading, and proper indexing.

What is lazy loading and when should I use it?

Lazy loading loads related objects only when accessed, which can save memory. Use it when you don't need all related data immediately.

Can you explain eager loading and its benefits?

Eager loading retrieves related objects in a single query, reducing the number of database hits. It's beneficial for performance when you know you'll need the related data.

What are some best practices for indexing in SQLAlchemy?

Best practices include indexing columns that are frequently queried, using composite indexes for multi-column searches, and avoiding over-indexing.
