could this fall back to generating from DB for complete streams that aren't in redis (so state == Complete && !(await redis.sIsMember('complete_streams', id))

otherwise seems good, will test locally in a bit

Problem is we don't know it's complete without consulting the DB - could make the logic if (!isInRedis) { fetchFromDB; if (isComplete) … }

yeah that would probably work; I'm mostly cautious about breaking all the catchup streams lol

[markspolakovs]

done that now
