[jira] [Created] (CASSANDRA-5044) Allow resizing of threadpools via JMX

Carl Yeksigian created CASSANDRA-5044:
-----------------------------------------

             Summary: Allow resizing of threadpools via JMX
                 Key: CASSANDRA-5044
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-5044
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Carl Yeksigian
            Assignee: Carl Yeksigian
            Priority: Minor
         Attachments: 5044.txt

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.
