Subject [jira] [Commented] (CASSANDRA-3706) Back up configuration files on startup
Date Wed, 09 May 2012 16:13:51 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-3706?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13271522#comment-13271522
] 

Jonathan Ellis commented on CASSANDRA-3706:
-------------------------------------------

bq. I'm not sure what last_yaml is if we're storing by digest

Why would we do that?  Just store the file raw.  Then you don't need FS access, is my point.

bq. also we're backing up 3 different files, not just yaml, but that's not a big deal

Yeah, I was kind of hoping the extrapolation would be obvious. :P

> Snapshot can backup user data, but it's also nice to be able to have known-good configurations
saved as well in case of accidental snafus or even catastrophic loss of a cluster.  If we
check for changes to cassandra.yaml, cassandra-env.sh, and maybe log4j-server.properties on
startup, we can back them up to a columnfamily that can then be handled by normal snapshot/backup
procedures.
