    Description

      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.
