Stefan Miklosovic commented on CASSANDRA-20854:
-----------------------------------------------
I highly encourage you to incorporate this (1). I have spend quite some time to
refactor it so it is "up to standards", hardened everything and so on. We need
this functionality a lot so I decided to help you with this patch a bit if you
do not mind.

> The [async-profiler|https://github.com/async-profiler/async-profiler] library
> is commonly used by the community to run low-overhead profiling on Cassandra
> processes due to its effectiveness and versatility.
> Following the discussion on [this
> thread,|https://lists.apache.org/thread/98y59qp42zwwrtbcvnzvlh254c5vyhoq]
> this library would be a great tool to integrate directly into Cassandra and
> expose via JMX accompanied by a convenient `nodetool profile` command.
