For example.
Assume column A has a global dictionary  encoding, and the dictionary is
{
      "AAAAA": 1,
      "BBBBB": 2,
      "CCCCC": 3
}
executor 1 return the result [1,2,3]
Finally the driver will replace the 1 to 'AAAAA', 2 to "BBBBB"?
The replace occurs in driver not executor?
If so, I want to ask why?
