Forwarding it here, someone with Cassandra internals knowledge can help may be....
Additionally, i observe the same behavior for reads too where Network read from one node is twice than other two.. ---------- Forwarded message ---------- From: Anishek Agarwal <anis...@gmail.com> Date: Tue, Apr 21, 2015 at 5:15 PM Subject: Network transfer to one node twice as others To: "u...@cassandra.apache.org" <u...@cassandra.apache.org> Hello, We are using cassandra 2.0.14 and have a cluster of 3 nodes. I have a writer test (written in java) that runs 50 threads to populate data to a single table in a single keyspace. when i look at the "iftop" I see that the amount of network transfer happening on two nodes is same but on one of the nodes its almost 2ice as the other two, Any reason that would be the case ? Thanks Anishek
