fn metric_sinks_on_replica(
metric_sinks: &BTreeMap<(ReplicaId, &'static str), InstalledMetricSink>,
replica_id: ReplicaId,
) -> Vec<&'static str>Expand description
The names of the definitions installed on replica_id, in key order.
The map is keyed replica-first, so a replica’s installs are one contiguous range.
