------------------------------
Summary: Input type annotation of MapTuple and FlatMapTuple are
ignored
Key: BEAM-14052
URL: https://issues.apache.org/jira/browse/BEAM-14052
Project: Beam
Issue Type: Bug
Components: sdk-py-core
Reporter: Yu Feng
This is a tracking bug for the remaining issue of type annotation support in
MapTuple and FlatMapTuple described in PR #16351.
Consider 2 cases:
- MapTuple(fn(a: int, b: int, *args))
- MapTuple(fn(a: int, b: int, args: Tuple[Any, ...]))
We unpack (1, 2, 3, 4) to a=1, b=1, args=(3, 4) in first case, but fail in
second case.
My concern is that the beam representation of these 2 signatures are *likely*
the same:
input_types[0] = (int, int, Tuple[Any, ...])
input_types[1] = {}
