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

Try using the below prconfig entries per your end and confirm if it helps:
<env name="dnode/cassandra_datacenter" value="DC1"/> <env name="dnode/cassandra_rack" value="rack2"/>
