-- Mejora #9: Caché de Stock con Redis
|
|
--
|
|
-- Adds Redis-backed stock caching for sub-millisecond lookups.
|
|
-- No database schema changes required — caching is handled entirely
|
|
-- in the application layer (pos/services/redis_stock_cache.py).
|
|
--
|
|
-- Invalidation strategy:
|
|
-- - Every stock mutation (SALE, PURCHASE, RETURN, ADJUST, TRANSFER, INITIAL)
|
|
-- invalidates the affected Redis keys immediately in Python code.
|
|
-- - Cache TTL is 5 minutes (configurable via REDIS_STOCK_TTL env var).
|
|
-- - On Redis miss, stock is computed from PostgreSQL SUM query and cached.
|
|
--
|
|
-- Prerequisites:
|
|
-- - Redis server installed and running (default: localhost:6379)
|
|
-- - redis-py library installed
|
|
--
|
