Optimization Tips
Add single_column index: add_index :users, :email - Fast lookups for email = value queries
Add covering index: add_index :users, ["email", "id", "name"], name: 'covering_idx_users_email' - Index-only scan without table access
Index Optimization - Review indexes on the 'users' table. Consider composite indexes for WHERE clauses.
