-- Слой ODS (Operational Data Store) — типизированные данные + дедупликация + DQ
|
|
-- ============================================================================
|
|
-- Назначение:
|
|
-- - Хранение типизированных данных для дальнейшей сборки DDS
|
|
-- - Дедупликация через ReplacingMergeTree (последняя версия по src_ingest_ts)
|
|
-- - Контроль качества: массив parse_errors для "грязных" данных
|
|
-- - Разделение: валидные строки → основная таблица, ошибки → *_errors
|
|
--
|
|
-- Важно:
|
|
-- - Наполнение ODS выполняется batch-процессом из sql/ods/20_stg_to_ods.sql
|
|
-- - Materialized View STG → ODS в target-state не используются
|
|
-- ============================================================================
|

-- ----------------------------------------------------------------------------
|

-- Удаляем legacy MV STG → ODS (если ранее были созданы)
