[zeromq-dev] Designing for a subscriber that only bothers when data is presented

Imagine a usecase having a persistent datastream form a pubsub but the
subscriber can't be bothered to receive messages in quiet times, just
because the data is not needed and is updated at such regular intervals
that processing messages at a given time is fast enough, while doing a
req/reply does give too much overhead at peak times.

Is using a subscriber with a very low highwatermark a smart design here,
or will it put a lot of presure on the publisher?
