Joris Van den Bossche commented on ARROW-9489:
----------------------------------------------
Ah, yes, a general "where" general seems more useful indeed, and can be used
for this purpose as well (and could also be used for some "setitem" like calls
in pandas, which would be useful to have)
> [C++] Add fill_null kernel implementation for (array[string], scalar[string])
