<p>
The process of matching duplicate profiles. If <code>Matching</code> = <code>true</code>, Amazon Connect Customer
Profiles starts a weekly batch process called Identity Resolution Job. If you do not specify a date and time for
Identity Resolution Job to run, by default it runs every Saturday at 12AM UTC to detect duplicate profiles in
your domains.
</p>
<p>
After the Identity Resolution Job completes, use the <a
href="https://docs.aws.amazon.com/customerprofiles/latest/APIReference/API_GetMatches.html">GetMatches</a> API to
return and review the results. Or, if you have configured <code>ExportingConfig</code> in the
<code>MatchingRequest</code>, you can download the results from S3.
