shaigoldman opened a new issue, #36267:
URL: https://github.com/apache/arrow/issues/36267
### Describe the bug, including details regarding any error messages,
version, and platform.
When a user is designing a get_schema() method for a FlightServer, the
expected usage is that it should return a "schema" instance, as it says on the
docs. However, the code actually raises an error if a schema is returned, and
requires you to return an instance of SchemaResult, a class only available from
the hidden pyarrow._flight module.
The bug is caused by lines 2059-262 of pyarrow._flight, in the method
_get_schema:
```
if not isinstance(result, SchemaResult):
raise TypeError("FlightServerBase.get_schema_info must return "
"a SchemaResult instance, but got {}".format(
type(result)))
```
I think this could be corrected by changing SchemaResult to Schema, and
parsing the Schema as a SchemaResult internally.
