<p>
The number of nodes in the DAX cluster. A replication factor of 1 will create a single-node cluster, without any
read replicas. For additional fault tolerance, you can create a multiple node cluster with one or more read
replicas. To do this, set <code>ReplicationFactor</code> to a number between 3 (one primary and two read
replicas) and 10 (one primary and nine read replicas). <code>If the AvailabilityZones</code> parameter is
provided, its length must equal the <code>ReplicationFactor</code>.
</p>
<note>
<p>
AWS recommends that you have at least two read replicas per cluster.
