<p>
A Boolean value that determines the read consistency model during the scan:
</p>
<ul>
<li>
<p>
If <code>ConsistentRead</code> is <code>false</code>, then the data returned from <code>Scan</code> might not
contain the results from other recently completed write operations (<code>PutItem</code>, <code>UpdateItem</code>
, or <code>DeleteItem</code>).
</p>
</li>
<li>
<p>
If <code>ConsistentRead</code> is <code>true</code>, then all of the write operations that completed before the
<code>Scan</code> began are guaranteed to be contained in the <code>Scan</code> response.
</p>
</li>
</ul>
<p>
The default setting for <code>ConsistentRead</code> is <code>false</code>.
</p>
<p>
The <code>ConsistentRead</code> parameter is not supported on global secondary indexes. If you scan a global
secondary index with <code>ConsistentRead</code> set to true, you will receive a <code>ValidationException</code>
.
