Subject Re: SSL & Streaming (#1567)
Date Tue, 22 Mar 2011 15:05:31 GMT
I see now that this is too new: and that it's
scheduled for the 0.8 release.

Is it right to assume the following from the accepted patch:

1.  keystore and truststore passwords are kept in clear text in the
cassandra.yaml ?
2.  It's all or nothing when it comes to inter-node communication over
SSL?  Meaning, nodes that are part of the ring that aren't configured
will start to fail if the configuration isn't changed?
3.  I only want to encrypt data from region 1 < -- > region 2 where a
vpn is not possible... data communication in the same rack for
example, is on a private network and shouldn't be encrypted (except
when it's ec2 ... i think it should be encrypted).  This is not
possible at the moment ... is there a plan for the future?

I do appreciate any feedback and don't mean this to come across in a
negative way.  Just trying to understand how far off it is from being
compliant in a security sense...
