T Jake Luciani commented on CASSANDRA-12490:

I'm pretty sure this also breaks read validation somehow.

If you write with a yaml profile and -pop seq=1..1000 then read with -pop 
seq=1..1m it will return without error. In 3.9 this errors as it should.

> When using the write command, cassandra stress sequentially generates seeds. 
> This ensures generated values don't overlap (unless the sequence wraps) 
> providing more predictable number of inserted records (and generating a base 
> set of data without wasted writes).
> When using a yaml stress spec there is no sequenced distribution available. 
> It think it would be useful to have this for doing initial load of data for 
> testing
