Hi All,
I am testing network topology strategy in cassandra I am using
two nodes , one node each in different data center.
Since the nodes are in different dc I assigned token 0 to both the nodes.
I added both the nodes as seeds in the cassandra.yaml and I am using

Anurag,
The Cassandra ring spans datacenters, so you can't use token 0 on both
nodes. Cassandra’s ring is from 0 to 2**127 in size.
Try assigning one node the token of 0 and the second node 8.50705917 × 10^37
(input this as a single long number).
To add a new keyspace in 0.8, run this from the
My understanding is that the replication factor is for the entire ring. Even
if you have 2 DCs the nodes are part of the same ring. What you get
additionally from NTS is that you can specify how many replicas to place in
each DC.
So RF = 1 and DC1:1, DC2:1 looks incorrect to me.
What is possible
Yeah, Narendra is correct.
If you have 2 nodes, one in each data center, use RF=2 and do reads and
writes with either level ONE or QUORUM (which means 2 in this case).
However, if you had 2 nodes in DC1 and 1 node in DC2, then you could use
RF=3 and use LOCAL_QUORUM for reads and writes.
