If a node is partitioned from the rest of the cluster (ie. the
Don't run with a replication factor of 2, use 3 instead, and do all reads
and writes using quorum consistency.
That way, if a single node is down, all your operations will complete. In
fact, if every third node is down, you'll still be fine and able to handle
all requests.
However, if two adjacen

I hope this explains it.

Ps, you may be getting a bit confused by the way. Just think if you have
a 10 node cluster and one node is down and you do CL=2Š..if the node that
is down is where your data goes, yes, you will fail. If you do CL=quorum
and RF=3 you can tolerate one node being downŠIf you use astyanax, I think

ANY: worked (expected...)
ONE: worked (expected...)
TWO: did not work (WHT???)
This is expected sometimes and sometimes not. It depends on the 2 of the
3 nodes that have the data. Since you have one node down, that might be
the one where that data goes ;).
THREE: did not work (expected...)
Hello All,
We have a 3-node cluster and we created a keyspace (say Test_1) with
Replication Factor set to 3. I know is not great but we wanted to test
different behaviors. So, we created a Column Family (say cf_1) and we
tried writing something with Consistency Level ANY, ONE, TWO, THREE,
QUORUM a
