Adam Holmberg commented on CASSANDRA-10007:
-------------------------------------------

Maybe something changed since alpha 1. I was specifically running on that release when I reported
it.

> We noticed an anomaly in paged results while testing against 3.0.0-alpha1. It seems that
unbounded selects can return rows repeated at page boundaries. Furthermore, the number of
repeated rows seems to dither in count across consecutive runs of the same query.
> Does not reproduce on 2.2.0 and earlier.
> I also noted that this behavior only manifests on multi-node clusters.
> The attached script shows this behavior when run against 3.0.0-alpha1.
