-- Batch-трансформация: STG → ODS
|
||
-- ============================================================================
|
||
-- Назначение:
|
||
-- - Перенос типизации STG → ODS из Materialized View в управляемый batch
|
||
-- - Полная пересборка ODS для прозрачного мониторинга в Airflow
|
||
-- - Сохранение DQ-логики: parse_errors + отдельные *_errors таблицы
|
||
--
|
||
-- Когда запускать:
|
||
-- - В DAG etl_pipeline перед ODS → DDS
|
||
-- - После загрузки очередного среза данных в Kafka/STG
