What happens when one of the IP in cassandra_contact_points fails?

Currently I have five IP addresses for each cassandra node. Lets say 1 or 2 of the cassandra node goes down, what’s the kong behavior in this case? Will kong know that it is not able to ping certain IP’s and it continue to work with the remaining nodes or the call will fail? My assumption is it should continue working but wanted to be sure on this.

Thank you,
Amol
