I have a cluster running which has 4 nodes. Each node has an EBS volume  
attached to it, where the node backs up all the indexes it has.

So,  
node1 =\> ebs 1  
node2 =\> ebs 2  
node3 =\> ebs 3  
node4 =\> ebs 4

Now I need to shut down node 4. Since the load is less on this cluster, I  
shut down one the node and have written a script to re spawn it when the  
load increases on the cluster or more memory is required.

So, in the case when the node4 is re-spawned, it will attach its ebs 4 and  
start loading all of these indexes stored in the shard.

Lets say some of the indexes which were initially with node 4 got updated  
after node 4 is down ( node 1 has a replicated copy and node 1 updates  
those indexes), then when node 4 is re-spawned, Will node 4 look for  
updates and then update the indexes in its shard? or will it read the shard  
and contain old indexes ( not updated) ?
