Sergey Kuksenko commented on CASSANDRA-15037:
---------------------------------------------
I have to say that hdr histogram doesn't work on Java 11 or later due to
absence of java.xml.bind module.
.....
Exception in thread "StressMetrics" java.lang.NoClassDefFoundError:
javax/xml/bind/DatatypeConverter
> cassandra-stress doesn't provide warmup for duration based executions
> ---------------------------------------------------------------------

> Key: CASSANDRA-15037
> URL: https://issues.apache.org/jira/browse/CASSANDRA-15037
> Project: Cassandra
> Issue Type: Bug
> Components: Legacy/Tools
> Reporter: Sergey Kuksenko
> Priority: Low
> Labels: stress
> Fix For: 4.0.x
>
> Attachments: stress_warmup.patch
>
>
> cassandra-stress utility performs warmup only when number of operations is
> specified.
> In case of duration based execution it doesn't provide warmup. That leads to
> count startup/warmup induced latency that maybe considered as undesired
> statistics.
> For example latencies difference between warmed and cold execution even for
> 15 minutes may reach to: 17% for 99th percentile, 35% for 99.9th and 55% for
> max latency.
>
> Attached patch contains example how it may be fixed. It was chosen to use 1/5
> of duration time as warmup time, but probably the proper way to do it is to
> add a new option.
