Hi Shawn, This method exists in the C++ implementation [1], so it is likely reasonable to expose some form in python (I couldn't find it either in pyarrow). This should be reasonable straight-forward (you could follow the path taken for read implementation) if it is something you wanted to contribute.
Thanks, -Micah [1] https://github.com/apache/arrow/blob/3694794bdfd0677b95b8c95681e392512f1c9237/cpp/src/arrow/ipc/writer.h#L169 On Mon, Oct 12, 2020 at 12:38 AM Shawn Yang <[email protected]> wrote: > I want to write a record batch as ipc message separately without writing a > schema.
