Why does fillnull command have two type processing? (distributable streaming command/dataset processing)

Splunk documentation said


"fillnull command is a distributable streaming command when a field-list is specified. When no field-list is specified, the fillnull command fits into the dataset processing type"

 

I wonder why it works as dataset processing if no fields are specified. The results are all the same anyway, but there must be a reason.

Thanks for letting us know.

When a field name is specified, it's easy for an indexer to see that the field has no value and substitute the fill value.  Without a field name specified, it has to know the full set of fields to know which have null values.  That's not a distributable function.
