The above command might timeout if you’re downloading images over a slow connection. If that happens you can always run it again. Send and receive messages. Once the cluster is running, you can run a simple producer to send messages to a Kafka topic (the topic will be automatically created):

HeaderConverter class used to convert between Kafka Connect format and the serialized form that is written to Kafka. This controls the format of the header values in messages written to or read from Kafka, and since this is independent of connectors it allows any connector to work with any serialization format.
