[Neo4j] Rest API in the future

2011-06-19 Thread Aniceto Perez
I have downloaded neo4-rest-graphdb, a rest wrapper for Java. README file says this interface does not support transactions. So we have: - EmbeddedGraphDatabase, which is good for tests, supports transactions and has quick communications. Not good for medium sized or HA apps because lacks

Hello Aniceto, - EmbeddedGraphDatabase, which is good for tests, supports transactions and has quick communications. Not good for medium sized or HA apps because lacks separation between app and data The EmbeddedGraphDatabase is fine for production use - in fact it's the default choice!

[Neo4j] More spatial questions

2011-06-19 Thread Nolan Darilek
Fortunately, recent changes seem to have made the memory leaks I was experiencing a few weeks ago to vanish. Apologies for not playing a more active part in these discussions, but I'm finding there to be a quite steep learning curve here, and I don't have the time to make a major push to

[Neo4j] ls command for trav in shell does not working

According to the neo4j-sh help, there is a -c option to the trav command that should allow for executing the ls command on each node visited in a traversal. -c Command to run for each returned node. Use $i for node/relationship id, example: -c ls -f name $i. Multiple commands can be

Hi Nolan, I think I can answer a few of your questions. Firstly, some background. The graph model of the OSM data is based largely on the XML formated OSM documents, and there you will find 'nodes', 'ways', 'relations' and 'tags' each as their own xml-tag, and as a consequence each will also have

[Neo4j] Multiple-source lowest-cost path search

2011-06-19 Thread Giacomo Bernardi
Hello everyone, could you advice on the best way to do the following in neo4j? Given: - a graph G=V, E on which each node has an associated positive cost - a subset of source nodes S in E. I'd like to build a second graph in which each e in (S-E) is connected to any one of the source nodes S via

[Neo4j] Category Nodes and Type Safety vs Performance and Scaling

2011-06-19 Thread Romiko Derbynew
Hi Guys, We currently thinking of how we can get type safety when we do queries, one thing we do is have a category nodes, so e.g. Here is a sample query IEnumerableUser list = g.v(0).outE[[label:'HOSTS']].inV[[Key:'MyCompanyName']].inE[[label:'IS_COMPANY']].inV So the part highlighted
