How to list all producers of a kafka cluster?

karottenbunker :

I am able to list all Kafka Consumer with KafkaAdminClient:

AdminClient client = AdminClient.create(conf);
ListTopicsResult ltr = client.listTopics();
KafkaFuture<Set<String>> names = ltr.names();

ArrayList<ConsumerGroupListing> consumerGroups = new ArrayList<>(client.listConsumerGroups().all().get());
ConsumerGroupListing consumerGroup = consumerGroups.get(0);

Is it possible to list all registrated producers in a similar way?

Giorgos Myrianthous :

In contrast to consumers, it is not possible to retrieve such information since Kafka brokers don't store any kind of information about the producers connected to them.
