Ahmet Altay updated BEAM-12626:
-------------------------------
Description:
In the following pipeline, side input values are always empty:
{code:python}
windowed = (
p
| beam.Create([('k', 1), ('k', 2), ('k', 20)])
| beam.MapTuple(
lambda k, v: beam.transforms.window.TimestampedValue((k, v), v))
| beam.WindowInto(beam.transforms.window.Sessions(10)))
windowed | beam.Map(lambda k, si: (k, si), beam.pvalue.AsIter(windowed))
{code}
The problem does not happen with FixedWindows, and in Java similarly formed
pipelines (side input with Sessions windows) are rejected
(https://github.com/apache/beam/blob/8463a054c1d7e2b7ee8d11e9569e065cb5e02196/sdks/java/core/src/main/java/org/apache/beam/sdk/transforms/windowing/Sessions.java#L97)
