Aleksey Yeschenko commented on CASSANDRA-8597:
----------------------------------------------
bq. i'm not sure what's meant here? it's a deterministic workload if you use
the -pop seq=1..N, except for thread interleavings and ancillary chances like
"select". Do you mean a deterministic non-uniform distribution? Deterministic
select behaviour?
Can't use in a user profile. Use case here: want exactly 1M cells in one
partition w/ 3 clustering columns (as in
https://issues.apache.org/jira/browse/CASSANDRA-6694?focusedCommentId=13908198&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13908198).
Can use uniform and get close, but overall w/ issues 1,2,3 it's very PITA.

> Some of the trouble people have with stress is a documentation problem, but
> some is functional.
> Comments from [~iamaleksey]:
> # 3 clustering columns, make a million cells in a single partition, should be
> simple, but it's not. have to tweak 'clustering' on the three columns just
> right to make stress work at all. w/ some values it'd just gets stuck forever
> computing batches
> # for others, it generates huge, megabyte-size batches, utterly disrespecting
> 'select' clause in 'insert'
> # I want a sequential generator too, to be able to predict deterministic
> result sets. uniform() only gets you so far
> # impossible to simulate a time series workload
