   Arrow's C++ API is not, generally, ABI compatible between releases. It's even possible that changing cmake flags could modify ABI compatibility.
   
   If I understand your use case (which I might not), what you probably want is the Arrow C data interface: https://arrow.apache.org/docs/format/CDataInterface.html
   
   In your C++ project you can export to the C data interface (e.g. `arrow::ExportArray`)  Then, in pyarrow, you can import from this (`pyarrow.array._import_from_c`).  Or you could go in the other direction.  I'm glossing over the details but that is the rough shape of it.
