Stored procedure: Encapsulated SQL logic. Syntax (Snowflake): CREATE PROCEDURE proc(args) RETURNS type LANGUAGE SQL AS $$ BEGIN ... END; $$; Execution: CALL proc(args); or via connector. Use for: Multi-step logic, transactions, error handling. Best practice: Keep logic thin; use for orchestration. In cloud warehouses, prefer dbt/s Airflow for pipelines; procedures for DB-specific logic. Document parameters and side effects. Why it matters: Design choices compound at scale—wrong approach can cause 100× overhead. Scalability trade-offs: Profile before optimizing; validate on sample then full. Cost implications: Suboptimal choices multiply at billion-row scale.
Red Flag: Generic textbook answers. Pro-Move: 'At scale we measured X, implemented Y, achieved Z%—validated and iterated.'
