Kouhei Sutou commented on ARROW-16340:
--------------------------------------
[~niyue] Thanks. How about using [the C data
interface|https://arrow.apache.org/docs/format/CDataInterface.html] / [the C
stream interface|https://arrow.apache.org/docs/format/CStreamInterface.html]
instead of {{arrow/python/pyarrow.h}}?
{code:cpp}
auto table = get_exec_context()->search(sql);
auto reader = arrow::tableBatchReader(table);
struct ArrowArrayStream c_stream;
auto status = arrow::ExportRecordBatchReader(reader, &c_stream); // TODO: Check
status
// Call the following Python code from pybind11 (sorry. I'm not familiar with
Python's C API):
// py_reader = pyarrow.ipc.RecordBatchReader._import_from_c(&c_stream);
// py_table = pyarrow.Table.from_batches(py_reader);
return pybind11::reinterpret_steal<pybind11::object>(py_table);
{code}
The C data interface and the C stream interface are included in Apache Arrow
C++.
