  # insert some data
  table.mutate_row 'myrow', {'colfamone:myvalue' => 'awesome value'}

  # get it
  puts t.get('myrow', 'colfamone:myvalue').first.value

  # get timestamp
  puts t.get('myrow', 'colfamone:myvalue').first.timestamp

  # convert binary value to 64 bit integer
  t.atomic_increment('myrow', 'colfamtwo:counter')
  puts t.get('myrow', 'colfamtwo:counter').first.to_i64

  # make a scanner
  s = t.create_scanner('myrow', 'colfamnone') { |row|
