Hi, Firstly if you're going to use the server, then *use the server* rather than wrapping your own. The server is built and tuned for production use cases. The WrappingNeoServerBootstrapper type can be used to wrap an existing instance of a database in server clothing. The use case for this,

So, using an embedded db is the only way to if you want one-shot deployment? It might be worth it to see how difficult it would be to write that component as a plugin to the build tool I use (Cake). If you use it that way, I'd advise you to do a lot of performance testing. I'd love to look

Hi all, I am using neo4j 1.5 java embedded. My traverser is a main java program http://pastebin.com/1ynVESbc which takes a db path as input. What it does is pretty basic : it follows my graph (which is a tree) and stores the ending leaves in a file. However it is quite big : I goes through
