Review comment:
The `max_view` field here I think is always 268435456? In that case
adding or not adding an offset to it probably doesn't make a large difference,
as the value is already huge. But this also point to a problematic spot. When
previously we limited our per-node emits when user passed in a limit, we won't
be doing that any longer and start emitting all the rows. I _think_ it should
be ok given that we the rexi streaming replies (acks) and cleanup happens
properly. But if it doesn't then this could add significant processing load on
the workers.
