Re: [Titan, Cassandra] Query performance degrades with network latency between Cassandra nodes

It depends on your replication factor. If you didn't set it explicitly, the default RF=1. As you add nodes and the data gets distributed across the Cassandra nodes, the coordinator may need to connect to another Cassandra node to find the data.

Datastax has the best docs on Cassandra. Read them while you can!

I am are observing that graph query performance degrades with increased latency between Cassandra nodes. We are using READ consistency level = ONE. I was assuming with CL as ONE, there is no traffic between Cassandra nodes for graph queries. I this assumption correct?
If not, am I missing something here?
