------------------------------------
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
