Benedict Elliott Smith commented on CASSANDRA-15512:
----------------------------------------------------
I alluded in [this
comment|https://issues.apache.org/jira/browse/CASSANDRA-15388?focusedCommentId=17015376&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-17015376]
that we probably need to prune the state space a little (you don't need to
prune many options to make it more tractable).

from CASSANDRA-15511 is how I would approach looking at the data once I have a
chance to run some comparisons (though this isn't a complete view). To some
extent, simply looking at what patterns occur (that jump out) is informative,
as is looking at isolating specific variables and looking at aggregate
statistics for them. Obviously, what can be usefully reported to Jira is even
more summarised, unfortunately, but it's informative particularly for
regressions versus baseline.
