title: How do I do routing for MySQL Read Replica?
body: <p>I have created 2 read replicas of my master mysql database on rds.</p>
  
  <p>now all 3 have different connection endpoints.</p>
  
  <p>1) does it mean that i have to manage random selection of these endpoints for my queries?</p>
  
  <p>2) further to confirm, does it mean that I have to ensure that all my sql write queries needs to be routed to master endpoint</p>
  
  <p>3) Is there any ways in which routing can be handled programmatically? ie db load balancing</p>
