Subject [jira] [Created] (CASSANDRA-3675) ship with -XX:+ExplicitGCInvokesConcurrent by default
Date Tue, 27 Dec 2011 00:42:31 GMT
ship with -XX:+ExplicitGCInvokesConcurrent by default

                 Key: CASSANDRA-3675
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Peter Schuller
            Assignee: Peter Schuller
            Priority: Minor

It's so much easier if you can safely tell people to trigger a full GC to discover their live
set (see CASSANDRA-3574), instead of explaining the behavior of CMS and what the memory usage
graph looks like etc etc. Shipping with {{-XX:+ExplicitGCInvokesConcurrent}} means this is
by default safe.

For people that have special needs like some kind of rolling compacting GC with disablegossip,
they are special enough that they can just change the VM options.
