Probably yes, if you also disabled any sort of failovers from the token-aware
client…
(Talking about this makes you realize how many failsafes Cassandra has. And
still you can lose data… :-P)

Ahoy the list. I am evaluating Cassandra in the context of using it as a
storage back end for the Titan graph database.
We’ll have several nodes in the cluster. However, one of our requirements is
that data has to be loaded into and stored on a specific node and only on that
node. Also, it
This may be hard because the coordinator could store hinted handoff (HH) data
on disk. You could turn HH off and have RF=1 to keep data on a single instance,
but you would be likely to lose data if you had any problems with your
instances… Also you would need to tweak the memtable flushing so

Essentially you want to turn off all the features which make Cassandra a
robust product ;-).
Oh, I don't want to, but sadly those are the requirements that I have to work
with.
Again, the context is using it
You seem to be well aware that you're not looking at using Cassandra for
what it is designed for (which obviously imply you'll need to expect
under-optimal behavior), so I'm not going to insist on it.
As to how you could achieve that, a relatively simple solution (that do not

Google up NetworkTopologyStrategy. This is what you want to use and it's
not configured in cassandra.yaml but when you create the keyspace.
Basically, you define your topology in
