    DataSource ds = new DatasetDataSource(datasetId, dataset, recordType, null, /*external dataset doesn't have meta records.*/
    Type.EXTERNAL_DATASET, dataset.getDatasetDetails(), context.getComputationNodeDomain());
    IDataSourcePropertiesProvider dspp = ds.getPropertiesProvider();
    AbstractScanOperator as = (AbstractScanOperator) op;
    deliveredProperties = dspp.computePropertiesVector(as.getVariables());
}
