N/A alembic context sqlalchemy create_engine pool warehouse db run_migrations_offline N/A N/A N/A N/A N/A 
    Run migrations in 'offline' mode.

    This configures the context with just a URL
    and not an Engine, though an Engine is acceptable
    here as well.  By skipping the Engine creation
    we don't even need a DBAPI to be available.

    Calls to context.execute() here emit the given string to the
    script output.

    Run migrations in 'online' mode.

    In this scenario we need to create an Engine
    and associate a connection with the context.
