Can we use any mediator to communicate Grafana with AmazonES

I am trying to connect Grafana with AmazonES i am getting few docs on the same.
Please share demo on the same.
Can we use any mediator to connect AmazonES with Grafana so instead of direct calling AmazonES we will send the data to that mediator and then we will connect with grafana to mediator.

Kindly suggest.
