Rich Rein commented on CASSANDRA-8381:
--------------------------------------
It would be extremely useful to have 1 or a few recent key values for each step
of the histogram.
This would allow developers to see partitioning sizes as a side affect of key
values and frequency correlated with partition sizes.
But the worse case sizes mentioned by matt is critical.
> CFStats should record keys of largest N requests for time interval

> Key: CASSANDRA-8381
> URL: https://issues.apache.org/jira/browse/CASSANDRA-8381
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Matt Stump
> Priority: Critical
>
> Isolating the problem partition for a CF is right now incredibly difficult.
> If we could keep the primary key of the largest N read or write requests for
> the pervious interval or since counter has been cleared it would be extremely
> useful.
