Subject [jira] [Commented] (CASSANDRA-10403) Consider reverting to CMS GC on 3.0
Date Wed, 14 Oct 2015 18:19:05 GMT


Paulo Motta commented on CASSANDRA-10403:

For some reason, {{}} is called before loading {{debian/}}
on {{debian/init}}. Since the init script already defines {{CASSANDRA_HOME}}, I assume it's
safe to also define {{CASSANDRA_CONF}} in a similar way. Another option would be to load {{}}
before sourcing {{}}, but I don't think this should be necessary because we're
dealing with pre-defined package directories (eg. /usr/share/cassandra and /etc/cassandra),
so it should be safe to define them in a static way.

> For smaller heap sizes G1 appears to have some throughput/latency issues when compared
to CMS. With our default max heap size at 8G on 3.0, there's a strong argument to be made
for having CMS as the default for the 3.0 release.
