[jira] [Commented] (CASSANDRA-13701) Lower default num_tokens

    [ https://issues.apache.org/jira/browse/CASSANDRA-13701?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16940498#comment-16940498 ] 

Michael Semb Wever commented on CASSANDRA-13701:
------------------------------------------------

With CASSANDRA-15260 committed we have the option of assigning it as default value (RF=3) and moving ahead with this ticket.

Any takers?

> For reasons highlighted in CASSANDRA-7032, the high number of vnodes is not necessary. It is very expensive for operations processes and scanning. Its come up a lot and its pretty standard and known now to always reduce the num_tokens within the community. We should just lower the defaults.
