 Persistence
 ~~~~~~~~~~~
 The ZooKeeper and Kafka cluster are deployed with ``StatefulSets`` that have a ``volumeClaimTemplate`` which provides the persistent volume for each replica. You can define the size of the volumes by changing ``dataDirSize`` and ``dataLogDirSize`` under ``cp-zookeeper`` and ``size`` under  ``cp-kafka`` in `values.yaml. <https://github.com/confluentinc/cp-helm-charts/blob/master/values.yaml>`__
