---------------------------------------
Summary: [C++] Add unary negative kernel
Key: ARROW-11950
URL: https://issues.apache.org/jira/browse/ARROW-11950
Project: Apache Arrow
Issue Type: New Feature
Components: C++
Reporter: Neal Richardson
Assignee: Eduardo Ponce
Fix For: 4.0.0
Related to ARROW-11945. So that you can have an expression like {{-col}}. You
can approximate this with doing {{0 - col}}, but I would guess it could be done
more efficiently.
