Matthias Vallentin updated ARROW-17839:
---------------------------------------
Description:
I'm running into the following issue:
{code:java}
pyarrow.lib.ArrowNotImplementedError: Unsupported cast to
extension<vast.address<AddressType>> from fixed_size_binary[16]{code}
Use case: I want to create a record batch that contains this type:
{code:java}
pa.struct([("address", AddressType()), ("length", pa.uint8())]){code}
Here, {{AddressType}} is an extension type that models an IP address
({{{}pa.binary(16){}}}).
Please find attached a self-contained example that illustrates the issue.
