[jira] [Created] (ARROW-1363) [C++] IPC writer sends buffer layout for dictionary rather than indices

Wes McKinney created ARROW-1363:
-----------------------------------

             Summary: [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
             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)
