Subject [jira] [Commented] (CASSANDRA-7057) Add ability to adjust number of vnodes on a node
Date Mon, 21 Apr 2014 16:29:17 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-7057?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13975689#comment-13975689

Brandon Williams commented on CASSANDRA-7057:
---------------------------------------------

You can handle balance with relocate, aka 'nodetool taketoken' but I don't think there's going
to be any way to add tokens without adding nodes, since we'd have to bootstrap the tokens
without actually putting the node into bootstrap, which makes the communication of which tokens
are bootstrapping impossible.

> Currently, once a vnode server is configured with a num_tokens value, there is no defined
process to to change the number of vnodes a node is responsible for.
> This could be useful for load adjustments when upgrading hardware in a server, or adjusting
the number of vnodes to affect node data balance.
