Hi All,  
Suppose if we have the cluster of three nodes, Can we use scroll\_id which we get from node\_1 and use the same on node\_2 to get the remaining result?

No it's not possible from a single scroll which needs to run on the same nodes/replicas for all requests. Though you can use the `slice` scroll to parallelize the execution of your request:

Hi @jimczi  
Thank you for your response. I think I was not clear in the question. What I meant was, I will do a scan and scroll on node\_1. I will take the scroll\_id which was returned in node\_1 and use that in node\_2?

Ok sorry I misread your initial question. Yes this is possible, as long as node\_2 belongs to the same cluster, you can send the next scroll query to any node, the scroll\_id contains all the required informations to redirect the request internally.
