<p>
The number of read replica nodes you want at the completion of this operation. For Redis OSS (cluster mode
disabled) replication groups, this is the number of replica nodes in the replication group. For Redis OSS
(cluster mode enabled) replication groups, this is the number of replica nodes in each of the replication group's
node groups.

<p>
The minimum number of replicas in a shard or replication group is:
</p>
<ul>
<li>
<p>
Redis OSS (cluster mode disabled)
</p>
<ul>
<li>
<p>
If Multi-AZ is enabled: 1
</p>
</li>
<li>
<p>
If Multi-AZ is not enabled: 0
</p>
</li>
</ul>
</li>
<li>
<p>
Redis OSS (cluster mode enabled): 0 (though you will not be able to failover to a replica if your primary node
fails)
</p>
</li>
</ul>
