--------------------------------
Summary: [C++] IPC: validate batch schema equals stream schema in
debug mode
Key: ARROW-16625
URL: https://issues.apache.org/jira/browse/ARROW-16625
Project: Apache Arrow
Issue Type: Bug
Components: C++
Reporter: David Li
This came up in a Flight/Flight SQL demo a colleague was working on; it was
possible to write a batch with a differing schema than what was stated for the
stream, which would lead to a decoding failure on the other side. It might be
useful in DEBUG mode to DCHECK this and fail-fast.
The error message could also be improved; {{ArrayLoader.GetBuffer}} could at
least return the index and the actual # of buffers
