Subject network bandwidth question
Date Wed, 20 Jul 2011 12:02:06 GMT
Hi All

We're trying to set up a Cassandra cluster (initially with 3 nodes). Each
node will generate data @ 32MB per second. What would be the likely network
usage for this (say with a replication factor of 3)?

I mean, if I use simple arithmetic, I can say 32MBps per node, and hence
96MBps in total as network traffic - but should I consider any other factors
(like handshaking or keep-alive packets)?
