I've been doing some testing and study of Neo4J. I did a relatively large load of my data set (which is small 5000 nodes). I was amazed on how fast he load and traversal work (sure it's a small data set). Never the less we one thing I noticed that closing transaction is pretty heavy.
Each node object I store has 4K of data in 1 node with 3-5 related nodes. Doing transaction for each node/relation is really bad on performance. Having the entire object saved in one transaction is much better (but still slow). Adding all objects in a single transaction is definitely the best option (with my limited data set). The problem is that outside of the test it's strange to surface the Neo transactions outside of the persistence layer. This is not really a neo issue but since the difference is so large, I was wondering if there is a nice way to do this? I understand that we can't nest transactions. What tricks can be used to hide the neo transaction needs from the rest of the application and still allow certain control on that. Should I be looking at JTA? Never used JTA...
