Jeff Jirsa commented on CASSANDRA-14436:
----------------------------------------
Asked for second review from [~iamaleksey] because this touches some internals
(notably the changes to the {{ReadExecutionController}} ) where someone with a
lot of familiarity with that code makes sense - also anything in the hot path
really deserves two reviewers at this point in the game.
> Add sampler for query time and expose with nodetool

> Key: CASSANDRA-14436
> URL: https://issues.apache.org/jira/browse/CASSANDRA-14436
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Chris Lohfink
> Assignee: Chris Lohfink
> Priority: Major
> Labels: pull-request-available
> Fix For: 4.0.x
>
> Time Spent: 0.5h
> Remaining Estimate: 0h

> Create a new {{nodetool profileload}} that functions just like toppartitions
> but with more data, returning the slowest local reads and writes on the host
> during a given duration and highest frequency touched partitions (same as
> {{nodetool toppartitions}}). Refactor included to extend use of the sampler
> for uses outside of top frequency (max instead of total sample values).
> Future work to this is to include top cpu and allocations by query and
> possibly tasks/cpu/allocations by stage during time window.
