    // Construct the primary key.
    PrimaryKeyBuilder primaryKeyBuilder = PrimaryKeyBuilder.createPrimaryKeyBuilder();
    primaryKeyBuilder.addPrimaryKeyColumn("id", PrimaryKeyValue.fromString("row1"));
    PrimaryKey primaryKey = primaryKeyBuilder.build();

    // Construct the row data to be deleted.
    RowDeleteChange rowDeleteChange = new RowDeleteChange("test_table", primaryKey);

    // Call the deleteRow method to delete the row data.
    DeleteRowRequest deleteRowRequest = new DeleteRowRequest(rowDeleteChange);
    DeleteRowResponse deleteRowResponse = client.deleteRow(deleteRowRequest);

    // Return the result.
    System.out.println("RequestId: " + deleteRowResponse.getRequestId());
    System.out.println("Read CU Cost: " + deleteRowResponse.getConsumedCapacity().getCapacityUnit().getReadCapacityUnit());
    System.out.println("Write CU Cost: " + deleteRowResponse.getConsumedCapacity().getCapacityUnit().getWriteCapacityUnit());
