Hi everyone!
I have two questions setting up a cluster of three nodes.

1.In a cluster with three nodes, in local.ini:

[couchdb]
uuid = VALUE

VALUE has to be different for each node or the same for all?

2. It is important to keep this uuid value between releases upgrades?

I have this doubt because at
https://docs.couchdb.org/en/latest/setup/cluster.html
it says "*Use the first UUID as the cluster UUID.*". I interpret it as a
single UUID for the entire cluster.
And at https://docs.couchdb.org/en/latest/config/couchdb.html#couchdb/uuid
says
"*Unique identifier for this CouchDB server instance.*". I interpret it as
a UUID for each node, I thinks this is the correct one.

Thanks!
