When adding a new node to a cluster, is there a way to prevent it from having
to copy all the data from the other nodes?
We tried to copy the data on disk from an existing node (one that had all the
data for the given indices), but it still copied everything. Is there a way to
make it update what is new only?
Thanks.

It doesn't copy everything, only what it needs to balance the shards.

So if a shard has been updated since the data copy, will it copy the entire
shard, or just update it?
