-----------------------------------------
Summary: 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
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.
