Hi,
I have a question about optimizing the disk space required by Neo4j.
Currently i have a Neo4j database contains 238796 nodes, 5418484 properties
and 1328479 relationships, the disk space taked by Neo4j is about 17 GB and
i think is too much. so is there any optimization can be considered to
Could you explain the number, types and sizes of the properties (distribution)?
Nodes take 9 bytes per node and rels 33 bytes on disk.
Simple properties up to a long take up 25 bytes, strings that don't fit into
the short-string compression and arrays take larger sizes in the stringstore
and
Hello Neo4J-Team,
does anyone looked into this issue? Any insights?
Thanks again,
Mathias

Hey guys,
I've been thinking that I would like to have a topic (like this current one)
where I would be allowed to post anything related to brainstorming on my
project which is currently a mix of neo4j and berkeleydb java edition. That
is, I would like to start from scratch and explain and
i face strange problems with this method , i am sure i am giving it the right
node id and the new properties , but i found the same old un-updated node in
the DB , also i followed the instructions regarding flushing and shutting
down the index
please can you help me?

Hi John,
I think when approaching a project there are two distinct issues at play, one
is the tooling level,
another is the actual solution you are trying to create for an actual problem.
When looking at the tooling level it is great to have as much covered as
possible.
Neo4j offers a graph
Hi Ahmed,
The best way for us to help is if you send a unit test that demonstrates the
problem you're having. Can you send some JUnit code please?

Hi John, Niels,
I think of indexes in Neo4j as long-lived names. Not quite the keep it local
that Niels mentioned, but not entirely dissimilar either.
Those long lived-names tend to give you starting points in the graph from where
you perform graph operations. Indexing therefore constitutes
Marko had a good line about this: graphs are adjacency free indexes (or words
to that affect).

Has anyone tried running Neoclipse with X11 Forwarding on a remote linux
server? Any pointers ?
It does not seem to work for me :(
Any other tips for inspecting remote database contents of embedded
installation, without the web admin ?

or you could try to use WrappingNeoServerBootstrapper which runs a neo4j-server
with an existing, embedded GraphDatabaseservice.
See this thread for context:

Good point.
It could for all practical purposes even be IterableRelationshipType so they
can be lazily fetched, as long as the underlying implementation makes certain
that any iteration of the RelationshipTypes forms a set (no duplicates).
There is no need to have RelationshipTypes in any
Interesting thought, and it is certainly true that indexing is much less of a
concern in a graph database than in a normal RDBMS where generally every table
needs to have a primary key and where you need to have an index on the primary
key to be able to do joins (at least to do them somewhat
Hey Niels, thanks for the concise reply.

To be exact its org.neo4j.app:neo4j-server:1.4, and its not posted on

Update and a question.
I was able to get the server JARs and run the WrappingNeoServerBootstrapper.
The problem is that after getting everything from maven it misses the
neo4j-server-static-web.jar. Its not a part of any POM and is not listed in
dependencies, nevertheless its required when
Runtime dependency is required for classifier 'static-web'. It should be
documented somewhere so that others will not find it out the hard way :)

Aiming to be as generic as possible can be good, but as some point you need to
be specific too.
You mention Java and Eclipse as being generic, but they are only to a point.
When Java was introduced some of its main feats were platform independence,

How can I check if there are unfinished transactions? I want to do the
same thing that is done when EmbeddedGraphDatabase is instantiated
after a non-clean shutdown.

Imho it would have to iterate as well.
As the type is stored with the relationship record and so can only be accessed
after having read it.
It might be to have some minimal performance improvements that relationships
would not have to be fully loaded, nor put into the cache for that. But this
