When to use each

alembic

Any production SQLAlchemy app. Column additions/renames, index creation, constraint changes, data backfills as part of schema migrations.

redis

Caching API responses or DB queries, session storage, rate limiting counters, pub/sub messaging, leaderboards (sorted sets), task queues (BLPOP), distributed locks.

When to skip each

alembic

Non-SQLAlchemy databases (use Flyway, Liquibase, or Django migrations). Throwaway dev DBs where you can afford to drop and recreate.

redis

Primary persistent storage — Redis is RAM-first and can evict data. Complex relational queries. Large blobs (Redis excels at small, fast values).
