What are some effective query optimization techniques in Django Rest Framework?
Some effective techniques include using select_related and prefetch_related to reduce database hits.
Can you explain how select_related works?
Sure! select_related is used for single-valued relationships and performs a SQL join to fetch related objects in one query.
What about prefetch_related? How is it different?
prefetch_related is used for multi-valued relationships and executes separate queries to fetch related objects, then combines them in Python.
Are there any other techniques I should know about?
Yes, consider using database indexing, query caching, and optimizing your serializers for better performance.
