fn metric_sinks_on_replica(
metric_sinks: &BTreeMap<(ReplicaId, &'static str), InstalledMetricSink>,
replica_id: ReplicaId,
) -> Vec<(&'static str, ClusterId, GlobalId)>Expand description
The registry entries installed on replica_id, as (name, cluster, sink) in key order.
The map is keyed replica-first, so a replica’s installs are one contiguous range.
