newEmbeddedDatabase api needs a path on file system. why cant it use in-memory?

Question

My need is to use neo4j embedded in my java appliation . As I do not want to store anything on file system, I want to create my database in-memory. Is it possible in neo4j when it is embedded in my java application?

just to be clear, you want to lose your data when your application shuts down, right? — Michal Bachman, Sep 21 '13 at 07:12

Run your graph db on a mountpoint using tmpfs and disable file buffer caches (use_memory_mapped_buffers=false).

You can use ImpermanentGraphDatabase if you want a temporary per request graph model. Or you can try TinkerGraph's in-memory capabilities and use Gremlin for querying/
