Cassandra 3.x High Availability - Second Edition

Connecting to the cluster

To get connected, you will start by creating a Cluster reference, which you will then construct using a builder pattern. You will specify each additional option by chaining method calls together to produce the desired configuration, then finally calling the build() method to initialize Cluster.

Let's build a cluster that's initialized with a list of possible initial contact points:

private Cluster cluster; // defined at class level 
// you should only build the cluster once per app 
cluster = Cluster.builder() 
   .addContactPoints("10.10.10.1", "10.10.10.2", "10.10.10.3") 
   .build(); 

Tip

You should only have one instance of Cluster in your application for each physical cluster, as this class controls the list of contact points ...
