Scanner interface allows application to scan a range of rows of a table. It is the caller's responsibility to close() the scanner after finishing using it. Scanner allows one to fetch the key without fetching the value to allow underlying implementation to instantiating tuple objects (Row) lazily.

Examples of org.apache.hadoop.zebra.io.TableScanner

    String projection = new String("a,b,c,d,e,f,r1,m1");
    
    BasicTable.Reader reader = new BasicTable.Reader(pathTable1, conf);
    reader.setProjection(projection);
    List<RangeSplit> splits = reader.rangeSplit(1);
    TableScanner scanner = reader.getScanner(splits.get(0), true);
    Tuple RowValue = TypesUtils.createTuple(scanner.getSchema());
  
    scanner.getValue(RowValue);
    System.out.println("rowvalue size:"+RowValue.size());
    System.out.println("read a : " + RowValue.get(0).toString());
    System.out.println("read string: " + RowValue.get(1).toString());
  
    scanner.advance();
    scanner.getValue(RowValue);
    System.out.println("read float in 2nd row: "+ RowValue.get(1).toString());
    System.out.println("done insert table");
  
    reader.close();
