HI Luca, I am developing an application that currently uses CouchDB, but I've just come across OrientDB and I see that it has some features I could really do with, like ACID transactions and the graph database.
But as Nick mentions in his posts above, I need a server to be disconnected from the main cluster for long periods, with users still being able to update and query that server. And when it is re-connected to the cluster, I want to merge the offline changes that were made to that server with the Leader. So it needs a 2-way replication between Server <--> Leader replication, rather than a 1-way Server <-- Leader. That is built into CouchDB, but is it possible with OrientDB? One of the difficulties with 2-way replication is resolving conflicts. In the OrientDB slide show from 2012, it talks about a plug-in conflict resolution strategy, and that the default is to mark conflicts in the Conflict Log and leave them to be resolved manually. But I haven't been able to find any other information on this, so I'm not sure if it will work in my scenario?
