Bulk loader is meant to load data quickly into a **new cluster**. You can do an export of your existing data set and use bulk loader to load the export into a new cluster along with your new data. The export data is in gzipped RDF NQuad format and the bulk loader can read from multiple rdf.gz files in the same directory.

If you want to load lots of new data into an existing cluster, you can use the live loader.
