public static interface Cluster.Initializer
Cluster
instances.
If you want to create a new Cluster
instance programmatically, then it is advised to
use Cluster.Builder
which can be obtained from the Cluster.builder()
method.
But it is also possible to implement a custom Initializer
that retrieves
initialization from a web-service or from a configuration file.
