Re: [Neo4j] Batch Inserter memory exception

Hi there, what is your Neo4j version and did you set any special JVM flags or neo4j.properties? Cheers, /peter neubauer GTalk: neubauer.peter Skype peter.neubauer Phone +46 704 106975 LinkedIn http://www.linkedin.com/in/neubauer Twitter http://twitter.com/peterneubauer

Re: [Neo4j] Minor convenience request: Cypher default console =)

Mmh, that sounds selfish indeed ;) However, maybe we should start thinking about preferences and saving of them in the webadmin (even for the visualization, last opened tab etc). Any thoughts there whether to have that saved in the client or in the server? Cheers, /peter neubauer GTalk

Re: [Neo4j] Cypher: node IDs

we need more info on, could you raise one at https://github.com/neo4j/community/issues to track this down? Cheers, /peter neubauer GTalk: neubauer.peter Skype peter.neubauer Phone +46 704 106975 LinkedIn http://www.linkedin.com/in/neubauer Twitter http://twitter.com

Re: [Neo4j] Cypher: node IDs

Aseem, this sounds like a parsing exception. Maybe there are characters escaped in REST, but not in plain Cypher. Is there a way you could create a graph with only one or two UUID nodes and reproduce the stack trace so we can look at it? Cheers, /peter neubauer GTalk: neubauer.peter Skype

Re: [Neo4j] aStar nullpointer

Hi there, do you have a testcase that can reproduce this? If yes, forking and providing it would be great, otherwise, just open a GIThub issue on https://github.com/neo4j/community if that is ok? Cheers, /peter neubauer GTalk: neubauer.peter Skype peter.neubauer Phone +46 704

Re: [Neo4j] API adventures in Scalaland

Yeah, GraphViz is a good compromise for small graphs, see http://docs.neo4j.org/chunked/snapshot/rest-api-graph-algos.html Cheers, /peter neubauer GTalk: neubauer.peter Skype peter.neubauer Phone +46 704 106975 LinkedIn http://www.linkedin.com/in/neubauer Twitter http

Re: [Neo4j] Spatial query with property filter

/gis/spatial/TestDynamicLayers.java#L60for some examples. Basically, you define a dynamic layer witha CQL query, which will return the subset of the full layer (e.g. a SimplePointLayer) that matches that query. Would that help? Cheers, /peter neubauer GTalk: neubauer.peter Skype
