Uwe L. Korn updated ARROW-1558:
-------------------------------
Description:
Select values where a boolean selection array is true. As a default, if any
values in the selection are null, then values in the output array should be
null.
The null behaviour does not need to be toggable, if the user wants to select
nothing in the case of null, then it is necessary to call
selection_array.fillna(false) first.
was:Select values where a boolean selection array is true. As a default, if
any values in the selection are null, then values in the output array should be
null. The null behaviour should be toggable as this may vary on the use case.
