Optimization Suggestions
- Use includes() or preload() to load associated records — Eliminate N+1 queries and reduce database load
- Use includes() to eager load associations — Eliminate N+1 queries and reduce database load
- Use joins() when you only need to filter, not access associated data — Eliminate N+1 queries and reduce database load
- Use preload() when you don't need to query on associations — Eliminate N+1 queries and reduce database load
-
Add composite index: add_index :users, ["active", "published", "approved", "created_at"]
— Efficient multi-column filtering
add_index :users, ["active", "published", "approved", "created_at"] -
Add single_column index: add_index :comments, :post_id
— Fast JOIN execution
add_index :comments, :post_id -
Add single_column index: add_index :posts, :user_id
— Fast JOIN execution
add_index :posts, :user_id -
Add single_column index: add_index :users, :active
— Fast lookups for active = value queries
add_index :users, :active -
Add single_column index: add_index :users, :approved
— Fast lookups for approved = value queries
add_index :users, :approved -
Add single_column index: add_index :users, :published
— Fast lookups for published = value queries
add_index :users, :published
