Hi,

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.

Thanks,  
Rajesh

why you assume that a bulk update prevents you from querying your data on the same node?

Thanks Sharon for your response

I don't want to do bulk upload on live node because we have index corruption when we are doing bulk index on the live node  
So we are thinking this approach(having 2 nodes) as an option.

Please suggest.

Thanks,  
Rajesh
