[jira] [Created] (ARROW-11932) [C++] Provide ArrayBuilder::AppendScalar

Ben Kietzman created ARROW-11932:
------------------------------------

             Summary: [C++] Provide ArrayBuilder::AppendScalar
                 Key: ARROW-11932
                 URL: https://issues.apache.org/jira/browse/ARROW-11932
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
    Affects Versions: 3.0.0
            Reporter: Ben Kietzman
             Fix For: 5.0.0


It would be useful to be able to append a Scalar (and/or ScalarVector) to an ArrayBuilder. For example, in https://github.com/apache/arrow/pull/9621#discussion_r587461083 (ARROW-11591) this could be used to accumulate an array of expected grouped aggregation results using existing scalar aggregate kernels
