Re: [Neo4j] JAXRS Server Extensions

Great! I'm looking forward to test the new version. Hi Miklós, Batch updates through the REST API will be supported from 1.4 M4 which should be released today - so no need to roll your own. Jim ___ Neo4j mailing list User@lists.neo4j.org

[Neo4j] JAXRS Server Extensions

Hello, I'm experimenting with my own server extensions to speed up batch querying and batch update of the graph. Part of my extensions are working as expected giving me significant performance boost on large queries. Now I'm trying to implement batch update of multiple nodes. I was thinking

[Neo4j] Concurrent graph usage, design guidelines

[Neo4j] server with big (huge?) graph

Hi all, I'd like to get ideas on how to handle a (relatively) big graph. My graph is stored in a neo4j server. The structure is simple but highly interconnected: - I have nodes containing longer texts - and I have many nodes containing tokens of those texts. Relationships connect tokens to

Re: [Neo4j] server with big (huge?) graph

Thanks for the response. Then my idea of a server plugin wasn't a bad idea, great. My next question is then: how do I traverse only a part of the possible sub-graph? I mean: let's suppose I start traversing from node 'A' and want to get all 2 length paths on relationships 'TYPE_X' and 'TYPE_Y'.

Hello, I just realized that the 1.2 distribution contains now the new version of the old REST server! Great news! I was using 0.8 for testing and now I want to migrate my codes to 1.2 and I got stuck. I extracted the zip and started the server from console. I can access it from browser at the

Hello, where can I find a detaled documentation on how to use JavaScript to write prune evaluators? I'm wondering if there is a way to limit the number of returned nodes based on item count? I don't want to accidentally download hundreds of MBs. Also I want to know the other possibilites of

Thanks for the detailed description. If I understand it well the current REST API doesn't support this kind of pruning? I didn't mention it last time but I'm accessing the DB through REST API. I'll have to wait for the next server release :) MikKi Miklos, to limit the number of returned

[Neo4j] REST - add to index

Hello, I'm trying to write basic functionality to test the capabilities of the neo4j REST standalone 0.8. Everything seems pretty obvious so far except for adding to index. I always receive HTTP 400 when I try to insert something to the index. I'm sending this to the server: POST

Re: [Neo4j] REST - add to index

It may be that you're missing quotations around the node URI (since the server expects JSON format). Look at http://components.neo4j.org/neo4j-rest/#Add_to_index for more information Thanks, this was the problem :) (I'm using that page as a reference, I just missed the quotation.)

Hi all, I'd like to ask about the status of neo4j REST transaction support. I'm using 0.8 and as far as I know it doesn't support it. Will it be supported sometime in the near future (beginning of 2011)? Or shall I search for something different than neo4j? Regards, MikKi 2010.05.20. 21:05
