Yes the loading is single-threaded. Its a simple app that performs bulk loading
using:
DatasetAccessorFactory.createHTTP(baseUrl+"/data”);
and for the first model to transfer:
DatasetAccessor putModel(graphName, m);
and for following models:
static void addToTransferBulk(final String graphName, final Model m) {
if (currentDataset == null)
currentDataset = DatasetFactory.createGeneral();
currentDataset.addNamedModel(graphName, m);
triplesInDataset += m.size();
if (triplesInDataset > initialLoadBulkSize) {
try {
loadDatasetMutex(currentDataset);
currentDataset = null;
triplesInDataset = 0;
} catch (TimeoutException e) {
e.printStackTrace();
return;
}
}
