The bulk loader only does anything special if the database is empty. Otherwise,

Can you group a number of iterations together together and load the group? That amortizes the transaction costs.

Or write the updates to a external file, then load that file.

OutOfMemoryError, but I store data for each iteration, the system is too
slow. So, I would like to know what is the best way to do this with Jena
