[GitHub] [arrow-rs] viirya commented on issue #1625: UnionArray::is_null incorrect

viirya commented on issue #1625:
URL: https://github.com/apache/arrow-rs/issues/1625#issuecomment-1112508202

   Java:
   https://github.com/apache/arrow/blob/b76caf4964dc96d20b72b21291052f459fa9c68a/java/vector/src/main/codegen/templates/UnionVector.java#L697-L704
   
   It mentions:
   
   > IMPORTANT: Union types always return non null as there is no validity buffer.
   To check validity correctly you must check the underlying vector.
   
   C++:
   Default `IsNull`: https://github.com/apache/arrow/blob/c70426f73326b3852d1bd7c31d98be4743f3fcba/cpp/src/arrow/array/array_base.h#L57-L62
   
   I don't see UnionArray has overridden implementation.
