You can put a Cassandra cluster behind a load balancer. One thing to be cautious of is the health check. Just because the node is listening on port 9160 doesn't mean that it's healthy to serve requests. It is required, but not sufficient.
The real test is the JMX values. Dave Viner On Mon, Dec 20, 2010 at 6:25 AM, Jonathan Colby <jonathan.co...@gmail.com>wrote: > I was unable to find example or documentation on my question.
