I want to implement clustering concept of elastic search.
My requirement is I want to have 2 nodes as Node1 & Node 2
My application will be talking with Node1 and any bulk updates will happen on Node2 which may take 2-3 hours to completion .
After this operation I want my Node1 to be synced with Node2 (Latest) Data.
With this search option for my application is always avaibale without any downtime.
Please suggest how can I achieve this.
