You can remove a node from the ring use nodetool removetoken (see
http://wiki.apache.org/cassandra/Operations), this will not stream data to the
other nodes. You would prob want to run repair to make sure everything was ok.
Not sure what your last question is.
Hope that helps.

Ok, so one question is, if I haven't made any writes at all, can I decommission
without delay? (Is there a "force drop" option or something, or will the
cluster recognize the lack of writes)?
I may be able to segregate writes to the "reference collection
Agree. Cassandra generally assumes a reasonable static cluster membership.
There are some tricks that can be done with copying SSTables but they will only
reduce the need to stream data around, not eliminate it.
This may not suit your problem domain but, speaking of the AWS infrastructure
how a
To some extent, the boot-strapping problem will be an issue with most
solutions: the data has to be duplicated from somewhere. Bootstrapping
should not cause much performance degradation unless you are already pushing
capacity limits. It's the decommissioning problem which makes Cassandra
somewhat
