Configuring the primary data center nodes
This content applies only to On-premises and Client-managed cloud environments
Configure your Cassandra cluster for redundancy, failover, and disaster recovery by creating a multi-data center deployment. First, add nodes to the primary data center by configuring the prconfig.xml file and deploying the Cassandra database.
- Update the prconfig.xml file with the following
configuration:where:
<!-- list all available Cassandra data centers --> <env name="dnode/cassandra_datacenters" value="DC1,DC2"/> <!-- specify current data center --> <env name="dnode/cassandra_datacenter" value="DC1"/>cassandra_datacenters– Lists the data center names that you want to use when the internal Cassandra cluster is deployed.cassandra_datacenter– Specifies the node data center.
- Start the application server.
- Enable the Decision Data Store service by adding primary data center nodes as
part of that service. For more information, see Configuring the Decision Data Store service
