[Neo4j] Neo4j: Now or Later

Hi, Currently considering neo4j. We know a graph DB is the right solution long term, but we need to get our app out fast and with minimal infrastructure overhead. We won't hit performance issues on SQL for at least 6 months, and we're iterating weekly, so while that may seem close, using unfamili

Re: [Neo4j] Traversal framework suggested change

Then I prefer the first set, doesn't hurt to be explicit. Simply reads better with less thinking imo. David On Thu, Nov 18, 2010 at 10:41 PM, Mattias Persson wrote: > Maybe instead: > > INCLUDE_AND_CONTINUE, > INCLUDE_AND_PRUNE, > EXCLUDE_AND_CONTINUE, > EXCLUDE_AND_PRUNE, > > because "stop" so

Re: [Neo4j] Traversal framework suggested change

Maybe instead: INCLUDE_AND_CONTINUE, INCLUDE_AND_PRUNE, EXCLUDE_AND_CONTINUE, EXCLUDE_AND_PRUNE, because "stop" sounds that the traverser is stopping, where it's really just stopping that particular branch, i.e. prunes that branch. Or maybe even: INCLUDE, INCLUDE_AND_PRUNE, EXCLUDE, EXCLUDE_AND_

Re: [Neo4j] Traversal framework suggested change

Fantastic! I have yet to try the implementation out, but I'm positive that it's an improvement. The only comment I have right now is the use of the word "SKIP". IMO it is ambiguous with respect to stopping vs excluding. I prefer EXCLUDE. Will try it out soon. Thanks Mattias! David On Thu, Nov 18,

Re: [Neo4j] JTA support for Neo

Chris, This sounds like some major progress! IMHO you should start a branch in the SVN so others can look at the code. Having the compatibility tests is great - there are other breaking test that Mattias and Johan are using to purposely break recovery on both the normal server and HA setups. They a

Re: [Neo4j] Questions on custom query using the index framework

There's also a problem going with the QueryContext approach... an IndexSearcher can be shared by multiple threads and multiple queries so using IndexSearcher#setSimilarity can't be done on a per-query basis. Setting a similarity in one query may also set it for another thread/query which might not

Re: [Neo4j] Questions on custom query using the index framework

Allright, then there probably have to be a configuration parameter for similarity, and maybe something in QueryContext as well (if you wouldn't use the configuration parameter). 2010/11/18 Samuel Feng > From > > http://lucene.apache.org/java/2_4_0/api/org/apache/lucene/search/Similarity.html > >

Re: [Neo4j] Questions on custom query using the index framework

Hi, To my understanding, if you use one Similarity in indexWriter, you should also use it in indexSearcher. And the scoring is not written during writing index, as it depends on the relationship between query terms and the indexed documents. It is calculated for each query. 2010/11/18 Mattias P

There is nothing fundamentally wrong with JSON (o.k. maybe a *few* things), but with the right structures, it or any format can be completely self-describing. I have found that including a bit of additional metadata in the content helps IMMENSELY for both loosely-coupled and tightly-coupled applica

Hi Jim, Yes I know what you mean, the "{}" are part of the JAX-RS specification. I hope that I am not too controversy :-) The Neo4j Rest server uses HTTP and JSON thats true, but it violates IMHO some of the REST principles. I think that a technical interface should contain, if the content is a

Re: [Neo4j] REST support for neo4j-spatial

Sounds fine to me. The main idea behind this suggestion is to support concurrent access and the new server component. I can think of many use cases where data is inserted in aa database from any type of client and the result is accessed via e.g. geoserver. Currently we'd use PostGIS for such an

Hi Christopher, > http://localhost:/node/1/relationships/in/{-list|&|types}" This is a URI template, inviting you to replace the {...} with values of your own. In this case it's giving you the opportunity to provide a list of ampersand separated types. Now I believe this URI template synt
