Subject [jira] [Commented] (CASSANDRA-5901) Bootstrap should also make the data consistent on the new node
Date Mon, 19 Aug 2013 23:28:53 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-5901?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13744500#comment-13744500

sankalp kohli commented on CASSANDRA-5901:
------------------------------------------

If you have stale data in one node before replacing another node, now the new node will bootstrap
from the node having stale data. This will cause now 2 nodes to have stale data rather than
one. And if you replace another node, the third one will also have stale data. 

You can even lose data this way in extreme cases.

> Currently when we are bootstrapping a new node, it might bootstrap from a node which
does not have most upto date data. Because of this, we need to run a repair after that.
> Most people will always run the repair so it would help if we can provide a parameter
to bootstrap to run the repair once the bootstrap has finished. 
> It can also stop the node from responding to reads till repair has finished. This could
be another param as well.
