Minbo Bae created BEAM-11883:
--------------------------------
Summary: Unsupported operand type with PeriodicImpulse
Key: BEAM-11883
URL: https://issues.apache.org/jira/browse/BEAM-11883
Project: Beam
Issue Type: Bug
Components: sdk-py-core
Affects Versions: 2.28.0
Reporter: Minbo Bae
{{PeriodicImpluse}} throws {{TypeError}} if {{Timetamp}} is used as
{{start_timestamp}} and {{stop_timestamp parameters}}.
With the following example,
{code:java}
import logging
from apache_beam import ParDo
from apache_beam import Pipeline
from apache_beam.options.pipeline_options import PipelineOptions
from apache_beam.transforms.periodicsequence import PeriodicImpulse
def run(argv=None):
options = PipelineOptions(argv)
with Pipeline(options=options) as p:
(p
| PeriodicImpulse() # By default,
# start_timestamp=Timestamp.now(),
# stop_timestamp=MAX_TIMESTAMP,
# fire_interval=360.0,
| ParDo(lambda x: logging.info('element: %s', x))
)
if __name__ == '__main__':
run()
{code}
Running with DirectRunner fails with the following stacktrace.
{noformat}
