Re: [Neo4j] Add to Index REST API Question
Kevin, could you provide the REST sequence you are doing, so I could reproduce the case? Basically, inserting a node, creating an index, adding the ndoe to it and retrieve it. Is that possible?

I am currently using a SQL database to manage this, but I know it won't scale the way I need it to, so I am looking to implement Neo4j as a solution. I am using the server and REST APIs and I've been able to create nodes, relationships, and properties with no problems. I have a couple of questions: 1) Since I will keep the SQL database as part of my app to store and manage other data elements (including some properties associated with the entities that will be in the neo4j db) is it better to: (A) add the neo4j node.Id value to my SQL database to use as a lookup when getting neo4j nodes, or (B) add a property to each node (i.e. an identifier from the SQL db associated with the entity/node), index it in neo4j, and then search/retrieve nodes by their property value? 2) My initial answer to question #1 was (B) and I have been trying to figure out the indexing functionality in neo4j but have hit a wall. I keep getting 404 errors when attempting to add a node to the index. I haven't been able to get the cURL command ( http://components.neo4j.org/neo4j-server/1.3.M02/rest.html#Add_to_index) to work either. Am I approaching this wrong? Any tips from anyone using the indexing REST API from .Net? I am running 1.3.M03.

Re: [Neo4j] Big index solutions?
No, things are not failing, it is just that in big insertion scenarios the index lookup when joining nodes together into relationships, there is often just an exact index needed in order to do that. We have good experiences with Lucene, but when importing e.g. big OpenStreetMap datasets, we need to run lookups during insertion, and we experience Lucene taking a lot of time in these cases. That is why I think exact lookups, like K/V stores, would be interesting in these scenarios, as an alternative. They _should_ perform better then Lucene.

Massimo: If you can produce a test case that reliably (or at least semi-reliably) reproduces this, that would of course be even better, but it doesn't hurt if I could look at the store files and try to deduce the problem in parallell. I'm working on it... will let you know soon. Thanks for the interest...

[Neo4j] Announcing Neo4j 1.3 “Abisko Lampa” M04
Greeting fellow graphistas, Keeping up with the release schedule, today we present the fourth milestone towards the 1.3 “Abisko Lampa” version of Neo4j. The most important feature of this release is of course the expansion of the storage layer to allow for even more entities, but also includes improvements on the testing methodology used for Windows builds and the REST interface for Indexing operations. As always, extended details are available in the announcement post, reachable at http://blog.neo4j.org/2011/03/neo4j-13-abisko-lampa-m04-size-really.html There you can read a comprehensive description of the new features, however a special mention must be made to the new store format. This milestone of Neo4j brings with it an updated store version that allows for an 8x increase in the possible number of Nodes and Relationships and 16x increase for the number of Properties. All this happens without increasing the size of the database so you can go right ahead and upgrade, certain in the knowledge that everything will be done in place. A few words of caution are in order, though. An upgrade will not happen unless you explicitly request it - just pass in the configuration parameter “allow_store_upgrade” as “true” - otherwise an exception will be thrown that advises you to do just that and your store will be left untouched. There are some additional requirements for the upgrade to succeed, such as less than 65536 RelationshipTypes stored, but if you do not satisfy those the upgrade procedure will inform you of what the exact problem is and leave your store untouched. Finally, note that after a successful upgrade your database will be unreadable by previous versions. So keep in mind that while safe, this is a one way procedure. You can find more details on the subject at http://docs.neo4j.org/chunked/milestone/deployment-upgrading.html We invite you to try out these new features and provide us with your ever valuable feedback. cheers, CG ___ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user

[Neo4j] Neo4j OSGI bundle
Hi, I'm planning to use Neo4j under OSGi framework. Because org.neo4j:neo4j defines the needed headers (in MANIFEST.MF), it can be deployed as a bundle on equinox or felix. Unfortunatelly, the bundle doesn't export any package so it's quite unuseful for me as my own bundle can't import them. I guess, at least neo4j bundle should have Export-Package directive in MANIFEST.MF file. Do you think these headers could be added in the next snapshot ? Thanks. ___ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user
