Blake Eggleston commented on CASSANDRA-15072:
---------------------------------------------
Are you seeing incomplete results like this in a real cluster? If so, what
consistency level are you reading and writing at?
The ccm script you have here _does_ return incomplete results, but it’s also
writing and reading at CL ONE (the cqlsh default), so that’s not unexpected. I
modified the script here to read and write at QUORUM, and haven't gotten any
incomplete results.

> Hello
> During an upgrade from 2.1.17 to 3.11.4, our application starting getting
> back incomplete results for range queries. When all nodes were upgraded
> (before upgrading sstables), we stopped getting incomplete results. I was
> able to reproduce it and listed steps below. It seems to require the random
> partitioner and compact storage to reproduce reliably. It also reproduces
> coming from 2.1.21 and 2.2.14.
