Upon careful perusal of documentation and tutorials, our team has a few open questions, and we would appreciate to have these clarified by a hands-on practitioner. a. Can there by more than one Producer in a Publish-Subscribe model? Yes b. More details on level of abstraction between Producer/Consumer. Is one aware of others identity and Zookeepers offering on same No, Consumers and Producers only need to know about the topic. Consumers belong to a “group” which allows many consumers to read from the same topic but only process each message once. c. Can multiple Producers send message to the same Topic Yes d. How long are messages retained in Publish->Subscribe model? Kafka has time and size based retention policies: https://www.baeldung.com/kafka-message-retention e. How are messages stored? On disk, possibly replicated: https://www.baeldung.com/kafka-message-retention Thanks and Regards C.
