[GitHub] [arrow] pitrou commented on pull request #13009: ARROW-602: [C++] Provide iterator access to primitive elements inside an Array

   > 1. I suggest we add begin/end methods to `ChunkedArray`
   
   That wouldn't work, because there are no specialized subclasses of ChunkedArray. We want the iterator to yield raw C values whose type is datatype-specific.
   
   > There is an [experimental MultipleChunkIterator](https://github.com/apache/arrow/blob/master/cpp/src/arrow/chunked_array.h#L194) that seems to not be used in the codebase.
   
   It's used by `ApplyBinaryChunked`.
