Hello! As far as my understanding goes, unless you are using 2.7 with its MVCC support, SQL is not transactional and it has no guarantees that your insert + update will work consistently. You could use DataStreamer with allowOverwrite=true to do that in controlled fashion, instead of SQL.
Other than that, if you don't care about consistency that much you could just parallelize your load.
