There are two things here:
The error you're getting is because you probably forget to close some
IndexHits somewhere, IndexHits that you haven't iterated all the way
through... could you check your code for such mistakes?
The other one that doCommit always seems to be invoked I just tried and
Is there a good way of ensuring the IndexHits, close?
Especially if I give out the IndexHits (perhaps in an IteratorWrapper) to
client code?
Thanks

Thanks for the info re: calling close on the indexhits object. We will wrap
that logic in a try/finally wherever we use index queries.

I get that too, but sometimes. I got the feeling that it relates to
the number of @Transactional annotations that get nested. I might be
completely wrong.
But I got rid of it by revising my annotations.

Hi Robert,
I took a look at this and the issue is that you are using the
OSMGeometryEncoder to decode the RTree nodes. And the GeometryEncoder is
designed to be specific to your data model, while the RTree internal data is
hard-coded into the RTree design. So there is no guarantee that any

every time i create a graph,it is a directed graph,such as A---B;but not
B---A
thx~~

In Neo, all relationships can be traversed in either direction.

Subject: [Neo4j] undirected graph
how to create
Hi there,
you always create directed edges. However, if you don't want to take
directions into account, just ignore the directions in your traversals
using
for ( Path position : Traversal.description()
.depthFirst()
.relationships( LIKES, Direction.BOTH )
.prune(
you mean that there are no differences between undirected graph and directed
graph in neo4j?

Jacopo,
do you have the source for this available somewhere? It's hard to
judge anything from the class files ...

Exactly.
Just treat a directed graph undirected by ignoring the direction of
relationships.

Hi Jeff,
What you are describing is a Friends-of-a-friend (foaf) traversal, which
are the friends of my friends, who are not my direct friends.
The best way to perform such a traversal is by using the traversal API:
n.traverse( Order.BREADTH_FIRST, // because we want to exclude the direct

Hmm ... I checked the code.
Hi,
I have just started using Neo4j. I was wondering if Connection Pooling has
been implemented in Neo4j ?
I could not find any helper classes or any sort of documentation on it.

No need for connection pooling, since there is a single instance of the
database connection that can be shared across threads.

Hello,I'm a newbie for Neo4j. Recently I visited wiki, got a lot of useful
information, but there are some questions blocking me.
1. In neo4j's api,every method is thread-safe. I want to ask if every
request for read or write to neo4j be queued,one by one processing.
2. config HA cluster by
