> `assert pa.DataType.__str__(ty) == "arrow.py_extension_type<int64>"` The problem is that this doesn't distinguish between different extension types with the same storage type. For example, two extension types representing UUIDs and IPv6 addresses, respectively, would get the same string representation (because both would be backed by a 16-byte fixed-size binary). I would be more useful if the string representation looked like `extension<arrow.py_extension_type<IntegerType>>`, where `IntegerType` is the Python class name. Optionally this could be made configurable as well. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
