This is only a potential suggestion, not an issue.
I think it could be handy to have a tdb2.tdbsync tool for synchronizing a TDB dataset with a rdf file(s). Something to use like this: tdb2.tdbsync --loc dataset data.nt, and will automatically delete/insert tuples to maintain the dataset updated with the changes in the file. It would be handy when batch processing a large number of tuples.
