Elasticsearch has a very handy dedicated file-based discovery system: https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-discovery-zen.html#file-based-hosts-provider It's similar to what Cassandra's built-in SimpleSeedProvider does, but it doesn't require to keep up-to-date the *whole* cassandra.yaml file and that could probably be simpler to dynamically watch for changes. Ultimately, there are plenty of external applications that could be used to pull-in information from your favorite service discovery tool (etcd, Consul, etc.) or configuration management and keep this file up to date, without having to need a plugin for every system out there.
