Jorge Leitão created ARROW-15747:
------------------------------------
Summary: [C++] Allow C stream interface to accept any array
Key: ARROW-15747
URL: https://issues.apache.org/jira/browse/ARROW-15747
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Jorge Leitão
It seems that the C stream interface in pyarrow currently requires the array to
be a StructArray.
I do not see this constraint in the spec
(https://arrow.apache.org/docs/format/CStreamInterface.html).
The error I get when I pass an Int32Array to it (declared on the schema):
{code:java}
Invalid: Cannot import schema: ArrowSchema describes non-struct type int32
{code}
It would be nice to support everything, like the C data interface.
