docstr: Merges all of the values from `keys` to 'destination-key' sketch.
  It is mandatory to provide the `num_keys` before passing the input keys and
  the other (optional) arguments.
  If `destination_key` already exists its values are merged with the input keys.
  If you wish to override the destination key contents use the `OVERRIDE` parameter.
