Hi,

we currently plan to add a second data center to our Cassandra-Cluster. I
have read about this procedure in the documentation (eg.
https://www.datastax.com/documentation/cassandra/2.1/cassandra/operations/ops_add_dc_to_cluster_t.html),
but at least one question remains:

Do I have to provide appropriate values for num_tokens dependent on the
number of nodes per data center, or is this handled somehow by the
NetworkTopologyStrategy?

Example: We currently have 12 nodes each covering 256 tokens. Our second
datacenter will have three nodes only. Do I have to set num_tokens to 1024
(12*256/3) for the nodes in that DC?

Thank you very much for your valuable input!

Kind regards
Björn Hachmann
