Hi Assem
The logical log file is where all changes to be performed to the store
are written out before they are actually applied - also referred to as
the Write Ahead Log. The file that hosts this is bound to a specific
size above which a rotation happens: a new file is created to host the
WAL, al
Thanks Yuanlong,
we will look at it as soon as we got some time!

Boris,
you are seeing the expected results through REST but not through the
Webadmin with this query? That sounds like a bug then.

Hi,
Thanks James. Here is how I would do it -- groupCount is not needed.
g.idx(index_name)[[key:value]].both.loop(1){it.loops < depth}.count()
Note: Be wary of this query. Make sure the branch factor of your graph is
sufficiently small or the depth to which you are exploring is sufficie
Remember that the default match is 0.5 e.g director~0.5 hence why it matches up
to two letter differences e.g ditectof, directors etc

Excellent... I did a code review and think this is a huge improvement over what

Peter, can you pull these changes, I no longer have the privs to do so.

I'm making use of the Neo4j REST API to power a website and was wondering if
there was any way to block access to the web admin interface. Currently the
DB is in read-only mode but the web admin panel is accessibly by anyone who
can stumble upon the URL.

Hi there,
you can block access to it by blocking the access to the URL
(localhost:.../webadmin) and even /db/manage. That requires probably
to set up apache and mod_proxy in front of the Neo4j server, but I
think that is a good idea in production scenarios anyway.

correct, but through the spatial plugin via rest not gremlin.

Boris,
could you please raise an issue in Neo4j Spatial so I can start
investigating this?
https://github.com/neo4j/spatial/issues?sort=created&direction=desc&state=open
so we can track it down. Please provide REST calls that work and that
don't, will add it to the integration testing :)
Cheers,
since neo4j just uses jetty, i think the simple solution would be add
option in neo4j shell script:
-Djetty.host=127.0.0.1 to make it only listen to local request. then
use ssh tunnel to expose service to designated machines.

Thanks Marko. A
That sounds good. Could you try it and report back? Would love to add
it to the manual and as a setting.

Thanks everyone, this gives me plenty to work with. Will report back.

tested the idea, it doesn't work. so i made simple changes to the
server code and diff is attached.
to change the binding ip of the webserver: add following line to
conf/neo4j-server.properties:
org.neo4j.server.webserver.address=127.0.0.1

Hey guys, quick question on indexing.
We track Amazon products in our db, and the way Amazon identifies its
products is with an Amazon Standard Identification Number (ASIN). The only
catch is that ASINs are only unique within a particular locale, and Amazon
has a few different locales (e.g. us, uk
We have an implementation of TransactionEventHandler
in the method beforeCommit() I would like to use getProperty("nodeType") ..
so I can take proper action.
Now in the case of a deletion event, it won't let me call it and throws an
exception.
I'm surprised by this exception has this is beforeCom
Do you believe that neo4j will be able to store between 20 - 30 billion
nodes ? I am talking about genomics data.

Akhil,
i theory, this should be possible, see
http://docs.neo4j.org/chunked/snapshot/capabilities-capacity.html .
However, with that number of nodes etc, you need probably very
specialized hardware to run any form of performant traversal over this
data. If you want to do this, I suggest you put up

Linan,
your diff didn't make it could you just issue an pull request for that.
And Peter should get you sign a CLA btw.

Hi Guys -
I'm trying to compile and run the "write test"
(https://svn.neo4j.org/laboratory/users/johan/write-test) from
http://wiki.neo4j.org/content/Linux_Performance_Guide, and I'm getting this
error:

Is there a newer version of this?
Thanks.

Hi James,
I initially gave this a go and it worked, but found I had cached version of
the parent pom in my local maven repo. Removing this I got the same issue
you had.
You can get this working by replacing the parent pom reference in the
pom.xml file with:
org.neo4j.build
parent-cent

Hi all,
I am using (the embedded version of) Neo4j together with a webapplication
(WAR file for Tomcat).
Does anyone know a PaaS provider (like CloudBees) that allow a local file
storage?
(This would be a simple solution beside implementing the Neo4j Server
REST interface and f.e. using a Neo4j H
To reply to myself:
I found out that i was able to get the properties of the to be deleted node
