Yes, that's totally fair. Usually, a step is a meaningful unit of work, such as a API call that performs an external state modification. Because each step is a fair chunk of work, and the overhead is just one write per step, this scales well in practice--as well as Postgres scales, up to 10K+ operations/second.

I feel like you can generalise this to any transactional key value system, which can scale better.
