BullMq with Serveless options

[or-opus]

We are leveraging BullMq in prod environment, we sometimes can have high pick which we cannot anticipate so we end up over provisioning our ElastiCache. That's why we consider Serverless solution.
Which Serverless option would work best for BullMq in production environment
ElastiCache Redis serverless? ElastiCache ValKey serverless? Or any other?

To the best of my knowledge, Upstash is the only serverless solution that currently works with BullMQ. Valkey serverless has some issues with executing lua scripts with multi, that as far as I know has not been resolved yet.

do not use use bullmq with Upstash redis if you are not using a fixed price service. it was hammering redis at 2000+ call per minutes. i really do not understand why do you need todo that??

Difficult to say as we do not know so much of your environment. It is possible to reduce the drain delay to reduce the number of calls to BZPOPMIN, but you do not explain in which scenario you are getting these calls... in a busy queue you could get thousands of calls per second.
