-- Migration v3.3: Materialized view part_vehicle_preview
|
|
-- Purpose: Pre-compute the "most recent vehicle" per part to eliminate
|
|
-- DISTINCT ON + 4 JOINs over vehicle_parts (254 GB, 2B+ rows) at query time.
|
|
--
|
|
-- Notes:
|
|
-- - CREATE MATERIALIZED VIEW without CONCURRENTLY (first creation).
|
|
-- - REFRESH MATERIALIZED VIEW CONCURRENTLY is possible after the unique index exists.
|
|
-- - Run with statement_timeout = 0; this may take hours on first creation.
|
|
|
