Hi Vlad
I would propose you looked at this as two questions. The second question is
easy:
What would be if I do
new OrientGraphFactory("remote:orientdb.node1.com/TestDistributedDatabase",
username, password).getTx()
?
This way I connect specific node and as I understand can play with data on
it, but what if I create new vertex, will it be replicate on the
orientdb.node2.com ?
The rules of this are based on the config of the nodes - if you have a
write quorum of 2 in a 2 node set up you can guarantee that if the write
succeeds that it has written to both. Alternatively if you have
hotAlignment set to true and the 2 nodes 'know' about each other in
distributed mode - then you know that both nodes will get synchronized
eventually even if the write quorum is only set to 1. You can also ensure
that you get read consistency (i.e. both nodes have the same value for a
vertex) by setting the read qourum to 2.
In regards to the other question on connecting to the cluster ... NO IDEA
.. would LOVE TO KNOW :)
