Hello : I have an upcoming requirement wherein I need to bulk upload to Elasticsearch at a massive scale. While I've seen instances of people claiming million writes per sec is supported, I couldnt find a resource on how this was quantified.

This is my configuration:

> 5 M4X4.Large Master/DATA Nodes  
> 2 M4.Large CO Nodes fronted by ELB which takes in Client Requests  
> 5:1 PRimary to Replica Shard.

Can someone let me know how would I get an understanding of the approximate Writes per second this config supports?

May I suggest you look at the following resources about sizing:
