Guillaume,
please try to reduce the memory mapped settings I provided, e.g by 30%.
You can also inspect your system how much free memory is reported when you're
running the neo4j test. This amount of memory can be added to the memory mapped
file caches.
Have you looked at the linux transaction
Retrieving data in constant time sounds very promising especially for routing
purposes. Did you allready have thoughts on algorithms that use hierarchies
or contraction of the network? In our students project we implemented some
approaches to reduce search space and have thoughts on the heuristics
Hi guys,
i think my question is pretty simple, but since i cannot find anything
in network about it i decided to ask you. I'm using SDG with
cross-store functionality. I have users which are persisted in the
relational database. User has Address and Address is stored in Neo4j.
Going further
First thanks to all of you for the hints and the detailed explanation of
Craig. Peter I was not into any code in detail yet, but I have had a look on
the (beta) wiki of Neo4j spatial.
Some more questions on the storage format of Neo4j: So the nodes, properties
and relationships are stored in
Hi Michael,
I tried to lower the values by 30% = same and then by 50% = same again.
(MapMemException)
Here is the message.log http://pastebin.com/bvhhZfjZ
My neo4j.properties looks like that :
neostore.nodestore.db.mapped_memory=100M
neostore.propertystore.db.arrays.mapped_memory=50M
Guillaume,
you still having problems or is the performance ok now? I think with
tweaking the 110 hops/ms can be upped to at least 500, since you are
not touching any indexes except in the beginning. However, that would
require to look at the underlying system and do some inspection. Let
me know if
Daniel,
of course you could use native external indicies instead of in-graph
structures, but then you loose much of the topology capabilities of a
connected graph. However, probably it's a good idea to provide some
example of that, too. Got a link to a good native RTree implementation
that could

I thought that 'neo4j start' ran the server database instead of wrapping
an embedded database, but the gremlin console in the webadmin service shows
that g is bound to an instance of

Does Cypher support count(distinct) type of queries?
Tero,
No, it doesn't yet. It's planned for, but won't make it into 1.5.

This is great news. I love that it uses context managers for transactions.

Hi Chris.
I don't mean to pressure, I write OSS myself and I know time is
available whenever it is, so i just have some quick questions about this
issue.
Basically I just need to decided whether to shelf this feature of our
project for now or if i can get any idea on how much work / how long
