memberlist fails in large-scale clusters about memberlist

[zhuohuashiyi]

No, I conducted experiments based on memberlist in a cluster consisting of thousands of servers. The real cause of the problem I mentioned is that the udp packet size of a single broadcast is limited, and memberlist's broadcast logic is to first populate the system data, that is, some node status information, and then fetch data from the user-defined broadcast queue to populate the udp packet. This logic is fine in a small cluster, but if the cluster scale increases, udp packets will be full of node status information, resulting in inconsistency at the user level.
