Jonathan Ellis commented on CASSANDRA-5044:

Do we actually support sizing these threadpools from yaml if we want to make the change permanent?

> Currently changing the size of threadpools is done using the config files. If resizing
a threadpool, the node needs to be taken offline.
> Adding resizing via JMX allows online tweaking. TPEs allow for moving the number of threads
up and down; moving down will take effect after a thread in the pool becomes idle.
