[jira] [Created] (ARROW-3087) [C++] Add kernels for comparison operations to scalars

Uwe L. Korn created ARROW-3087:
----------------------------------

             Summary: [C++] Add kernels for comparison operations to scalars
                 Key: ARROW-3087
                 URL: https://issues.apache.org/jira/browse/ARROW-3087
             Project: Apache Arrow
          Issue Type: New Feature
          Components: C++
            Reporter: Uwe L. Korn
             Fix For: 0.11.0


This should implement the comparison operators  {{>=, >, ==, !=, <, <=}} between {{arrow::compute::Datum}} and {{arrow::compute::Scalar}}. 

The result of this kernel will be a boolean type {{arrow::compute::Datum}} where with True/False set according to the outcome of the operation and NA if a row was not valid.

A pre-condition to implement this kernel is to have a working implementation of {{arrow::compute::Scalar}}.
