title: How to setup read replica for Aurora Serverless
body: <p>I have global user base spread globally. If I use AWS Aurora MySQL Serveless DB, and select Multi-AZ support, how to use read replica closer to the user for RO queries.
  To be more specific, Primary DB will in London.
  London User -&gt; London App Server --&gt; London DB (for read)
  Tokyo user -&gt; Tokyo App Server --&gt; Tokyo DB (for read)</p>
  <p>London/Tokyo user -&gt; London/Tokyo App Server --&gt; London DB (for write)
  All I want to understand is how to force App SErver to connect to the nearest read replica.</p>
