Exporter exporter = Exporter.withOptions(exportOptions);
exporter.exportTo(schemaFile);

Import Data

// import data from a json file
ImportOptions importOptions = new ImportOptions();
importOptions.setNitriteFactory(() {
    MVStoreModule storeModule = MVStoreModule.withConfig()
        .filePath('/tmp/test-old.db')
        .build();

    return Nitrite.builder()
        .compressed()
