title: Is any aws service suitable for sending real time updates to browser?
body: <p>I'm developing a stocks app and have to keep users browser updated with pricing changes</p>
  
  <p>I don't need to access past data, browser just have to get current data whenever it changes</p>
  
  <p>is it possible to filter a dynamodb stream and expose an endpoint (behind api gateway) that could be used with a javascript EventSource?</p>
