> If a collection's shard contains dead replicas, write latency to the
> collection is increased. For example, if a collection has 10 shards with a
> replication factor of 3, and one of those shards contains 3 replicas and 3
> downed replicas, write latency is increased in comparison to a shard that
> contains only 3 replicas.
> My feeling here is that downed replicas should be completely ignored and not
> cause issues to other alive replicas in terms of write latency.
