use of com.aerospike.client.cluster.Partitions in project aerospike-client-java by aerospike.

the class Command method getSequenceNode.

private final Node getSequenceNode(Cluster cluster, Partition partition) {

    for (int i = 0; i < replicas.length; i++) {
        int index = Math.abs(sequence % replicas.length);
        Node node = replicas[index].get(partition.partitionId);
