Hi All, I've been reading up on neo4j's scaling features, and would love to confirm with some devs about the following: 1. Is it correct that neo4j's scale-out feature (HA) is NOT available in the community version (I'm using 2.2)? This is an easy one from the docs, but just wondering if ther

Sharding a graph is something that is often reasonably easy to do for specific domains (based on knowledge of the domain), but very hard to do generically for all domains. For this reason, while it has been considered for a long time, neo4j has not supported built-in partitioning of the graph. Uns

Each instance holds the _full_ graph. That way you achieve zero copy failover and high performance traversals which have never to cross the network. Michael On Wed, Jun 4, 2014 at 1:06 AM, Bernardo Hermont wrote: > Hi Stefan, > > Thank you for your e-mail. > So there is not a way of each clust

Hi Stefan, Thank you for your e-mail. So there is not a way of each cluster member storing only part of the graph, I mean, to have more control over each part is stored on each cluster node? I ask this just to see how exactly Neo4j fits into my requirements right now. Thank you again, Berna

Hi, Neo4j's clustering model is a master-slave replication. Each cluster member has a copy of the full graph enabling doing read operations without cluster intercommunication - and therefore scales reads almost linearly. Cheers, Stefan 2014-06-02 2:35 GMT+02:00 Bernardo Hermont : > Hi all, > > I

[Neo4j] Neo4j Sharding

Hi all, I have the following questions about Neo4j Is it possible to inform which slave node I want to store data that it is inserted using PUT REST interface? Or the data is automatically sharded along the slave servers that are part of the cluster? Is there any way to do this in a clustered
