Subject [jira] [Commented] (CASSANDRA-10007) Repeated rows in paged result
Date Wed, 19 Aug 2015 17:29:46 GMT


Steve Wang commented on CASSANDRA-10007:

Hi Benjamin! Yes, I'm still able to reproduce this error. What I do is start a 3 node cluster
in CCM and then run the script that Adam attached in this ticket. The first
two values are as expected, but the next few values, which should be 100, oscillate between
104 and 103.

> 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.
