Think of your domain model graph as a kind of index. Traversing that should
generally be faster than a generic index like lucene. Of course some things
do not graph well, and you should use lucene for those. But if you can find
something with a graph traversal, that is likely the way to go.
Also
Super,
you need to install http://www.assembla.com/wiki/show/scala-ide or
similar if you want to have Scala support in Eclipse.
Otherwise, it seems maven is handling things correctly now?

You could modify the structure of how the collection is stored so
there are several chains that can be updated in parallel for each
collection. Kind of how ConcurrentHashMap works with several locks.

Hi
I've been testing neo4j by creating a graph with +3M nodes and +3M
relationships on an Embedded database. I commited tx after 2K nodes and
2k relationships, but finally I got out of permgen space. It was a crash
test, so it didn't matter. Every node and relationship had one indexed
Nicolas,
thanks for looking into this! If you only move the LuceneDataSource
into an exported package, for instance org.neo4j.index.lucene, and
export it, would that be sufficient to get the registration done?
I don't want to force OSGi upon all Index provider bundles (yet) and
keep the impact of
If you iterate through all nodes and get all relationships in only ONE
direction e.g. OUTGOING you get every relationship only once. So this is just a
three liner.

Hi Peter,
As shown below, exporting the implementation package is enough to make the

exception comes later when registering the index. I guess this come from the

Hi Boris,
You need to build these plugins against the server-api package:

Once they're built, you just drop the jars in the $NEO4J_HOME/plugins

As one of the legacy users of the in-graph Timeline index, I have concern over
the future of this component.
Right now the in-graph Timeline index is part of the component neo4j-index,
which also contains the legacy Lucene index.
This component has a dependency on Lucene 3.0.1, while Neo4J 1.4

Hi Peter,
Thanks for the positive feed back.
I think it would be best to call this component Neo4J-collections, or something
to that extent, so data structures more constrained than a property graph can
be maintained. The BTree (Timeline index) is one such example, the RTree from

Could I use Cypher as a command-line query language like Gremlin? It would be
massively helpful if I just want to try some stuff in command-line and not
implement a whole method or class for just that. Just a thought. :)

Hi there,
last Friday I added support for Cypher in the Neo4j Shell, and an
example in the docs, see

How can we use online backup in Neo4J to do a hot backup to another local

It seems that the only way to instantiate the OnlineBackup class is something

A couple index framework questions:
