Re: [Neo4j] Multi-master server architecture
Kynao, Neo4j HA is right now a multiple slaves - single write master architecture that will have a write guarantee on 2 nodes if you write to a slave - the slave itself and the master. While this is good and stable for failover and read-heavy production scenarios, in the next version of Neo4j (2.x) we are looking at actually sharding the graph more dynamically than a Dynamo ring, especially runtime, on different machines, so we kind of hop over the stage of having configurable guarantees in a dynamo replication cluster in order to reach the dynamic graph sharding stage faster. HTH?

Re: [Neo4j] Multi-master server architecture
Thanks Peter for your answer. While my thinking were different from dynamo too and i'm still searching where part of my explanation are too incomplete or fails, good news about orientation taken in release 2.x, it will be very interesting to know how it works. Yes, your answer helps :) Regards On Fri, Sep 16, 2011 at 5:09 PM, Peter Neubauer peter.neuba...@neotechnology.com wrote: Kynao, Neo4j HA is right now a multiple slaves - single write master architecture that will have a write guarantee on 2 nodes if you write to a slave - the slave itself and the master.
