Hi, Nils.
We've implemented something like this here at ThingWorx, but we had to do so at
a layer above Neo4J since there, of course, were no built-in faceting
capabilities. One of the major challenges we faced was the opaque connection
from the Neo4J API to the underlying Lucene engine.
FWIW, we use Neo4J also as our dependency graph in ThingWorx. We can
determine deep, two-way dependencies quite easily, so that when any object in
ThingWorx is modified, we can intelligently do hot updates to affected
entities without having to stop and restart the entire server. It would
...though there are perfectly good reasons to include business logic on the
server as well (e.g. stored procedures, which Neo4J can support in its own way
via server-side extensions).

We do that today. It works fine. Here's a simple version of what we do:
- We created an AMI that contains our app server + app (which embeds neo)
- For each instance that we provision on EC2 using that AMI, we create an EBS
volume, and mount it to that instance
- We use a consistent
Take a look at the RelationshipType interface. If you implement that (which is
really simple - just a name() property), you can have your own class that can
have relationships with any names you want. They do need to be unique, however.

Hi, Michael.
Are you thinking maybe of lazily loading relationships in 1.5? That might be a
huge boost.

you have a
fixed schema and how to store new relationships between different
nodes. Its really difficult to understand how can you store
relationships only once in a model graph and only nodes in the data
graph?

Seems like all versions of Neoclipse now display *all* properties on nodes,
regardless of what you configure for property names in the graph decorations
configuration dialog. This pretty much renders Neoclipse unusable. :(

That's basically what we do - wrappers around our Location, InfoTable (2D data
table), DateTime (JODA), JSON, and XML entities to perform those types of
comparator actions for filtering and sorting. We also expose methods in the
wrappers (which also include Double, Boolean, String, etc.) to
Wow. Neo4J is optimized for keys to find certain nodes or relationships which
normally are not more than a dozen. That's quite a surprise to me, and I hope
it not to be the case!
