Cassandra Rack awareness with Pega

Hello,

does Pega support for internal Cassandra the rack awareness configuration?

Usually, Cassandra supports the following configuration to enable rack awareness:

all cassandra.yaml
endpoint_snitch: GossipingPropertyFileSnitch


DDS-node-1: cassandra-rackdc.properties
dc=dc1
rack=rack1

DDS-node-2: cassandra-rackdc.properties
dc=dc1
rack=rack2

DDS-node-3: cassandra-rackdc.properties
dc=dc1
rack=rack3

DDS-node-4: cassandra-rackdc.properties
dc=dc1
rack=rack1

DDS-node-5: cassandra-rackdc.properties
dc=dc1
rack=rack2

DDS-node-6: cassandra-rackdc.properties
dc=dc1
rack=rack3

All key spaces except system key spaces need to be switched to NetworkTopologyStrategy
  ALTER KEYSPACE <KEYSPACE> WITH REPLICATION = {'class' : 'NetworkTopologyStrategy', 'dc1' : 3};

How do we need to configure Pega to enable rack awareness in Cassandra? 

Regards

Maik
