Subject [jira] [Created] (CASSANDRA-8186) Revisit defaults for max rpc threads
Date Fri, 24 Oct 2014 18:12:34 GMT
Jeremy Hanna created CASSANDRA-8186:
---------------------------------------

             Summary: Revisit defaults for max rpc threads
                 Key: CASSANDRA-8186
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-8186
             Project: Cassandra
          Issue Type: Improvement
          Components: Core
            Reporter: Jeremy Hanna


Currently the rpc max threads defaults to unlimited.  The dangers of doing that in certain
circumstances were discussed on CASSANDRA-8116 and a warning was added to the yaml.

I've worked with two clusters in the last couple of weeks that has had the heap full of rpc
threads for this reason.  I'm wondering if we should set a more reasonable default so that
people don't hurt themselves unnecessarily.

Is there a reason to not default this to perhaps 2048, what's commented out in the yaml? 
We could have a yaml comment about it as well.
