------------------------------
External issue URL: https://github.com/apache/arrow/issues/17393
> [C++] IPC writer sends buffer layout for dictionary rather than indices
> -----------------------------------------------------------------------
>
> Key: ARROW-1363
> URL: https://issues.apache.org/jira/browse/ARROW-1363
> Project: Apache Arrow
> Issue Type: Bug
> Components: C++
> Affects Versions: 0.6.0
> Reporter: Wes McKinney
> Assignee: Wes McKinney
> Priority: Major
> Fix For: 0.7.0
>
>
> This is because of:
> https://github.com/apache/arrow/blob/master/cpp/src/arrow/ipc/metadata.cc#L321
> Since the buffer structure of record batches contains only indices, this
> should be the buffer layout in the IPC metadata.
> We should double check that Java is doing the right thing (I believe it is)
