CLUSTER_IDis required, as Azure event hubs does not provide a cluster ID when making an admin client request. The
CLUSTER_IDmust be unique across all clusters defined in kPow, and can be any unique identifier (eg, the namespace name of your event hub)
KAFKA_VARIANT=EVENT_HUBSenvironment variable must be set to
trueas Event Hubs does not support the topic configuration of
-1(which is set by kPow's audit log + Kafka Streams internal topics). Topics that normally have infinite retention will have a 7 day retention set in Event Hubs.
