["Aleksey Yeschenko (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-18027?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17631697#comment-17631697 ] 

Aleksey Yeschenko commented on CASSANDRA-18027:
-----------------------------------------------

A lot has changed since that initial JIRA was created. Is G1 what we want to use anymore? Should it be ZGC? Shenandoah is also at least worth mentioning.

If G1, are those the default params we want to use with our trunk?

> G1GC is well battle tested now, and the recommended configuration for most users. CMS can work well on smaller heaps but requires more tuning, initially and over time. G1GC just works. CMS was deprecated in JDK 9.
