Production-grade media metadata backend per docs/aurora-core-spec.md: Aurora-owned UUIDv7 identity system, normalized movie/TV/people/credits schema, provider abstraction with a TMDb adapter, an idempotent async ingestion pipeline (normalize -> match -> upsert -> provenance), a Postgres FTS/trigram search layer, a stateless FastAPI v1 API with Redis caching/rate-limiting, arq workers, dev/prod Docker Compose topologies, unit + integration + load tests, CI, and architecture/ database/API/ERD documentation.

"""Redis connection management.
|
|
|
|
Redis is disposable acceleration/coordination — caching, rate limiting,
|
|
distributed locks, and the arq job queue. It is never the system of record.
|
|
If `REDIS_REQUIRED` is false, the application degrades gracefully (caching
|
|
becomes a no-op, readiness does not depend on Redis) instead of failing when
|
|
Redis is unavailable.
