Multiple data centers

In practical scenarios, we would want to have Cassandra clusters distributed across different data centers so that the system is more reliable and resilient overall to localized network snags and physical disasters.

Prerequisites for setting up multiple data centers

The following are a set of prerequisites that should be used for setting up multiple data centers:

  • Have Cassandra installed on each node

  • Have the IP address of each node in the cluster

  • Identify the cluster names

  • Identify the seed nodes

  • Identify the snitch that is to be used

Installing Cassandra data centers

The following are a set of steps to set up Cassandra data centers:

  1. Let's start with an assumption that we have already installed Cassandra on the following nodes:

    10.188.66.41 (seed1)

    10.196.43.66

    10.188.247.41

    10.196.170.59 (seed2)

    10.189.61.170

    10.189.30.138

  2. Assign tokens using the token generation Python script defined in the previous section to each of the preceding nodes.

  3. Let's say we align to the following distribution...
