How to avoid nodes to be quarantined in Akka Cluster?

The doc of Akka Remoting (Artery) describes quarantine as follows: enter image description here Nodes will be quarantined when remote failure detector triggers in Akka Remote, but will not in Akka Cluster.

The doc of Akka Cluster describes quarantine as follows: enter image description here Nodes will be quarantined when there are too many unacknowledged system messages, but will not be quarantined when failure detector triggers.

So I have 3 questions:

  1. In Akka Cluster, failure detector triggers don’t cause nodes to be quarantined, so what are their roles?
  2. “too many unacknowledged system messages”, what’s the number of “too many” ? Can we addjust it ?
  3. How to config in Akka Cluster to make nodes will not or be harder to be quarantined ?

Thanks in advance.
