I also tried to implement the same logic in python as follows, but prism
does not get stuck when running this pipeline.
```python
import apache_beam as beam
from apache_beam.options.pipeline_options import PipelineOptions
from apache_beam.transforms.periodicsequence import PeriodicImpulse
from apache_beam.transforms.window import FixedWindows
from apache_beam.utils.timestamp import Timestamp
options = PipelineOptions([
"--job_server_timeout=600",
"--environment_type=LOOPBACK",
"--runner=PortableRunner",
"--job_endpoint=localhost:8073",
])
class InitCount(beam.DoFn):
def process(self, element):
return [1]
class PlusOne(beam.DoFn):
def process(self, element):
print(element)
return [element + 1]
HALF_MAX_TIMESTAMP = Timestamp(
micros=2147483647 * 1000 / 2 )
duration=5
fixed_window = FixedWindows(size=duration)
with beam.Pipeline(options=options) as p:
unboundedSource1 = p | "s1" >> PeriodicImpulse(fire_interval=duration)
unboundedSource2 = p | "s2" >>
PeriodicImpulse(start_timestamp=HALF_MAX_TIMESTAMP, fire_interval=duration)
trigger1 = unboundedSource1 | "w1" >> beam.WindowInto(fixed_window)
trigger2 = unboundedSource1 | "w2" >> beam.WindowInto(fixed_window)
c1 = trigger1 | "i1" >> beam.ParDo(InitCount())
c2 = trigger2 | "i2" >> beam.ParDo(InitCount())
_ = ([c1, c2] | beam.Flatten() | "p1" >> beam.ParDo(PlusOne()) | "p2" >>
beam.ParDo(PlusOne())) | "p3" >> beam.ParDo(PlusOne())
```
