Specifies whether to create standby instances for the DB shard group. Valid values are the following:
</p>
<ul>
<li>

0 - Creates a single, primary DB instance for each physical shard. This is the default value, and the only one
supported for the preview.

<li>
<p>
2 - Creates a primary DB instance and two standby instances in different AZs for each physical shard.
