Subject [jira] [Commented] (CASSANDRA-11550) Make the fanout size for LeveledCompactionStrategy to be configurable
Date Thu, 14 Apr 2016 06:14:25 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-11550?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15240675#comment-15240675

Marcus Eriksson commented on CASSANDRA-11550:
---------------------------------------------

My biggest concern is that adding more configuration options can confuse users and it requires
us to do more testing etc

To add this option we would need some real-life improvements, so please report back if you
get good results with your experiments!

> Currently, the fanout size for LeveledCompactionStrategy is hard coded in the system
(10). It would be useful to make the fanout size to be tunable, so that we can change it according
to different use cases.
> Further more, we can change the size dynamically.
