" The series makes endpoint state map in the gossiper addressable by host id instead of ips. The transition has implication outside of the gossiper as well. Gossiper based topology operations are affected by this change since they assume that the mapping is ip based. On wire protocol is not affected by the change as maps that are sent by the gossiper protocol remain ip based. If old node sends two different entries for the same host id the one with newer generation is applied. If new node has two ids that are mapped to the same ip the newer one is added to the outgoing map. Interoperability was verified manually by running mixed cluster. The series concludes the conversion of the system to be host id based.
