Subject Attaching a virtual DC
Date Wed, 21 Mar 2012 15:58:23 GMT

I need to attach a virtual DC to an existing cluster. My existing
cluster uses the Ec2Snitch as endpoint_snitch in cassandra.yaml.
Since both my clusters will live in the same AZ in AWS, it seems as
though my best bet is to switch to a property file snitch to divide.

A couple of questions:

* My restarts are very slow due to the poor IO on EC2, do I have to
restart existing nodes or can I juste use the propertyfile snitch on
the new virtual DC nodes ?
* To correctly replicate I need to update my placement strategy to
networktopology strategy, again no need to restart for this operation,
right ?
