David, Thank you so much for the explaination and suggestion. What I meant by dynamic was, we would not have all the data initially to load at once. Bulk of the data (Nodes/Relationships) would be loaded by users of the application by uploading spread sheets into the application on a regular(say daily/weekly) basis. So I was wondering if there was a way to switch between BatchInserter & GraphDatabaseService within the application to take advantage of BatchInserter's superior performance for bulk inserts. Honnur

And keep in mind that the BatchInserter should only be used from a single thread. You could of course build your own GraphDatabaseService that delegates to these two implementations, but you'd have to take the threading aspect into mind. And you'd have to re-instantiate the EmbeddedGraphDatabase for caching reasons though, and then you'd lose your whole cache. So I'd say, just go with EmbeddedGraphDatabase. Please explain the "dynamic" usage and your scenario more.
