Re: [Neo4j] Persistent vs in-memory storage

Hi, Neo4j requires a filesystem and that filesystem may be mounted in RAM or not. You can only control the location of the graph store through the API but it has to be on a supported filesystem. On Linux a in memory graph db can easily be created using /dev/shm: GraphDatabaseService inMemoryG

Since it is volatile you could remove the synchronized on getGraphDatabase() but if your app depends on getting null graphdb when context has been destroyed you would have to rewrite the contextDestroyed to something like: public void contextDestroyed( ServletContextEvent event ) {

Re: [Neo4j] neo4j spatial bounding box vs. lat/lon

Hi, The bounding boxes are used by the RTree index, which is a typical way to index spatial data. For Point data, the lat/long and the bounding box are the same thing, but for other shapes (streets/LineString and Polygons), the bounding box is quite different to the actual geometry (which is not j

Thanks! So it seems you are saying that the bounding box represents a single point and is the same as the lat/lat lon? What if I make the bounding box bigger? What I am trying to do is geo queries against a bounding box made of a set of points, rather than individual points. So the query is, find t

I think you need to differentiate the bounding boxes of the data in the layer (stored in the database), and the bounding box of the search query. The search query is not stored in the database, and will not be seen as a node or nodes in the database. So if you want to search for data within some bo

So what version of Lucene are you on? After I upped my version of Lucene (to 3.2.0) my problem went away. If you're using Maven, you might also want to check for duplicates (mvn dependency:tree > out.txt and look for multiple entries of Lucene). Eelco On Tue, Jun 7, 2011 at 10:08 PM, Super Wang
