Example 1 with Clusters

the class ControlPlane method getKafkaClusters.

 * Get the current list of ManagedKafka clusters from the control plane
 * as a blocking call.
 * Also updates the cache of desired state ManagedKafka instances.  May include
 * entries that have not yet been created locally.

 * @see {@link #getDesiredStates()} to get the full cache, rather than making a
 * remote call
