decreaseReplicationFactor method

Future<DecreaseReplicationFactorResponse> decreaseReplicationFactor({ required String clusterName, required int newReplicationFactor, List<String>? availabilityZones, List<String>? nodeIdsToRemove, })

Removes one or more nodes from a DAX cluster.

May throw ClusterNotFoundFault. May throw NodeNotFoundFault. May throw InvalidClusterStateFault. May throw ServiceLinkedRoleNotFoundFault. May throw InvalidParameterValueException. May throw InvalidParameterCombinationException.

Parameter clusterName : The name of the DAX cluster from which you want to remove nodes.

Parameter newReplicationFactor : The new number of nodes for the DAX cluster.

Parameter availabilityZones : The Availability Zone(s) from which to remove nodes.

Parameter nodeIdsToRemove : The unique identifiers of the nodes to be removed from the cluster.
