Thanks for answer, @tustvold. Now I understand some aspects. Perhaps I need to learn more about many features of Arrow :) > The array into_builder methods are fallible and can only be used where it can be guaranteed there are no shared references to the underlying buffers, I suspect they will therefore be of limited utility to DataFusion which is not setup to provide these guarantees The argument is clear to me, but there are some arrays for which this function is not implemented and is not dangerous: `BooleanArray`, `FixedSizeBinaryArray`, `NullArray`. Do we need to implement these methods for them, or is it still not worth adding extra code? -- This is an automated message from the Apache Git Service.
