Ah , got it. To rephrase the answer to my question, considering the same property
min.insync.replicas <https://kafka.apache.org/documentation/#min.insync.replicas> Type: int Default: 1 Valid Values: [1,...] Server Default Property: min.insync.replicas Importance: medium As the document says, *Server Default Property* specifies the corresponding broker property that will be used if no value is mentioned for this property ( at the topic level) by considering the rules of https://kafka.apache.org/documentation/#dynamicbrokerconfigs. Other interesting example where topic property is different from broker property. - cleanup.policy . While cleanup.policy <https://kafka.apache.org/documentation/#cleanup.policy> is topic specific property while equivalent server ( broker) property is log.cleanup.policy Hope my understanding is inline.
