--------------------------------------
Summary: [C++] Refactor StringTransform
Key: ARROW-12951
URL: https://issues.apache.org/jira/browse/ARROW-12951
Project: Apache Arrow
Issue Type: Task
Components: C++
Reporter: Antoine Pitrou
Currently, there is a non-trivial inheritance relationship between
{{StringTransform}} and its derived implementation classes. Also, the derived
classes have to be templated on the actual string type even though their code
doesn't care, making generated code size probably bigger than it should be.
Instead, there could be a {{StringTransformExec}} class that delegates to an
independent class for per-kernel specifics (mostly: the {{MaxCodeunits}} and
{{Transform}} methods).
