Re: [Neo4j] Set property on node in Neo4j REST server
Hi Peter,
For the specific case of updating a single property then:
PUT node/{node_id}/property/{property_key}
with an entity body like:
some text
or
27
would be OK I think
But not until the 1.6 M01 release :-)

Re: [Neo4j] Graph Data Corruption?
Thanks John, on what platform and file system do you run this? 2011/10/17 Tatham Oddie tat...@oddie.com.au As a sidenote, relationships are traversed in either direction with equal performance. Having reciprocal relationships is unnecessary. (Unless you can have person A support server B *without* server B being supported by person A ... but that just sounds broken.) I agree, server X supported by person Y can (and should) be inferred from person Y supports server X. It's more expensive to have duplicated relationships. -- Tatham -Original Message- From: user-boun...@lists.neo4j.org [mailto:user-boun...@lists.neo4j.org] On Behalf Of John Howard Sent: Sunday, 16 October 2011 12:00 PM To: Neo4j user discussions Subject: Re: [Neo4j] Graph Data Corruption? Thanks Mattias for the response. Yes, these nodes are consistently getting the same exceptions. Initially I thought shutting down the graph gracefully and starting it would solve the issue, but it didn't. We inserted node/relationships/properties with the regular create operations and NOT using the BatchInserter. Our dataset has 6 domains, one of them is People which has relationships to all other domains. Each node and relationships have about 8-12 properties.

Is there a way to solve this problem? Then, how much is fast the neo4j-REST traverser compared with the Java embedded traverser on a 3 million nodes graph? Cheers!

[Neo4j] Index Creation via REST API
Hello,
trying to work RESTfully with Neo4j via Standalone Server (1.5.M01) I'm
about to become desperate.
I'm sending an POST-Request to
http://localhost:7474/db/data/index/node/, getting status-code 500 with
the response-text java.lang.Boolean cannot be cast to
java.lang.String.
The indexes I've wanted to create are the following one:
{name:address,config:{provider:lucene,type:fulltext}}
{name:user,config:{provider:lucene,type:fulltext}}
Neo4j log contains the following line:
17.10.2011 16:56:10 org.mortbay.log.Slf4jLog warn
FATAL: /db/data/index/node/
java.lang.ClassCastException: java.lang.Boolean cannot be cast to

Whats wrong with this requests and in case this is an known bug at the

Re: [Neo4j] Index Creation via REST API
This looks right. Can you create the error with a curl call so I can
recreate it?

Re: [Neo4j] Configuring Neo4J via Python bindings
Hey Jake, Awesome! Thanks so much for making this happen! On my end, it doesn't look like the docs are up yet. I'll check back... Thanks again, Chris On Mon, Oct 17, 2011 at 4:12 AM, Jacob Hansson jacob.hans...@neotechnology.com wrote: Hey Chris, I've just added support for passing in extra JVM args, it's available as of this commit: https://github.com/neo4j/python-embedded/commit/d41950f8c7e6c65d67f60868976e1864a496a2ea Documentation will pop up in an hour or so here: http://docs.neo4j.org/chunked/snapshot/python-embedded-reference-core.html This feature will be available as of the 1.5 release, due later this week. If you want to get access to it right away, you can build neo4j-embedded directly from source, the code is available here: https://github.com/neo4j/python-embedded See the readme for how to build from source.

We use Linux platform and am not sure about the file system, I guess it's the regular one!

Having reciprocal relationships is unnecessary. (Unless you can have person A support server B *without* server B being supported by person A ... but that just sounds broken.) I agree, server X supported by person Y can (and should) be inferred from person Y supports server X.

Thanks Mattias for the response. Yes, these nodes are consistently getting the same exceptions. Initially I thought shutting down the graph gracefully and starting it would solve the issue, but it didn't. We inserted node/relationships/properties with the regular create operations and NOT using the BatchInserter. Our dataset has 6 domains, one of them is People which has relationships to all other domains. Each node and relationships have about 8-12 properties.

It happened on a node's relationship and we deleted that relationship and related node, so we were able to access the node and all its relationships.
