Subject [jira] [Commented] (CASSANDRA-12490) Add sequence distribution type to cassandra stress
Date Thu, 13 Oct 2016 19:37:22 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-12490?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15572941#comment-15572941

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
