An array of one or more global secondary indexes for the table. For each index in the array, you can request one
action:
</p>
<ul>
<li>
<p>
<code>Create</code> - add a new global secondary index to the table.
</p>
</li>
<li>
<p>
<code>Update</code> - modify the provisioned throughput settings of an existing global secondary index.
</p>
</li>
<li>
<p>
<code>Delete</code> - remove a global secondary index from the table.
</p>
</li>
</ul>
<p>
You can create or delete only one global secondary index per <code>UpdateTable</code> operation.
