Optimization Tips
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 single_column index: add_index :comments, :post_id - Fast JOIN execution
Add single_column index: add_index :posts, :user_id - Fast JOIN execution
Add single_column index: add_index :users, :active - Fast lookups for active = value queries
Add single_column index: add_index :users, :approved - Fast lookups for approved = value queries
Add single_column index: add_index :users, :published - Fast lookups for published = value queries
Add single_column index: add_index :users, :created_at - Efficient range scans for created_at
Consider breaking complex query (complexity: 18) into smaller parts - Easier maintenance and potentially better performance
Index Optimization - Review indexes on the 'users' table. Consider composite indexes for WHERE clauses.
