Hi All,

From Cassandra paper "http://www.cs.cornell.edu/projects/ladis2009/papers/lakshman-ladis2009.pdf": "Cassandra is configured such that each row is replicated across multiple data centers."

So, while using multiple data centers, is it required to have almost same number of Cassandra nodes in each data center. If not, would it generate key hotspots?

Thanks,
Sunil
