Welcome! Please see the About page for a little more info on how this works.
The transactor provides a configurable cassandra cluster callback, but the peers do not. The Cassandra driver depends on old versions of metrics libraries that are incompatible with newer versions used in (for example) clojure metrics. Datastax solution for this requires use of the cluster callback https://docs.datastax.com/en/developer/java-driver/3.5/manual/metrics/#metrics-4-compatibility, but that isn't available in Peers.
