Andrew Wieteska commented on ARROW-8173:
----------------------------------------
I *think* these type checks have now been implemented:
https://github.com/apache/arrow/blob/65aa527707d7067bff833bd744ebfd97f1c2c909/cpp/src/arrow/chunked_array.cc#L67-L84
> [C++] Validate ChunkedArray()'s arguments
> -----------------------------------------
>
> Key: ARROW-8173
> URL: https://issues.apache.org/jira/browse/ARROW-8173
> Project: Apache Arrow
> Issue Type: Bug
> Components: C++
> Affects Versions: 0.16.0
> Reporter: Ben Kietzman
> Priority: Major
>
> ChunkedArray has constraints on type uniformity of chunks which are currently
> only expressed in comments. At minimum debug checks should be added to ensure
> (for example) that an explicit type is shared by all chunks, at best the
> public constructor should be replaced with
> {{Result<std::shared_ptr<ChunkedArray>> ChunkedArray::Make(...)}}.
