[jira] [Created] (ARROW-15747) [C++] Allow C stream interface to accept any array

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.
