pitrou opened a new pull request #11280: URL: https://github.com/apache/arrow/pull/11280
Union and Null types don't support a validity bitmap according to the buffer layout spec: https://arrow.apache.org/docs/format/Columnar.html#buffer-listing-for-each-layout However, Arrow C++ internally stored an empty null bitmap buffer for these types. We must therefore be careful not to export this buffer accross the C data interface. On import, we support both layouts for compatibility. -- This is an automated message from the Apache Git Service.
