delayed emit (timer) in py-beam?
What's going on with timers and python?
Am looking at building a pipeline (assuming another group in my company
will grant access to the Kafka topic):
Kafka -> beam -> have beam wait 24 hours -> do transform(s) and emit a
record. If I read things correctly that's not currently possible in python
on beam. What all is needed? (trying to figure out whether that is
something that I am capable of and there is room for me to help with).
Looking for similar functionality to https://www.rabbitmq.com/blog/
2015/04/16/scheduling-messages-with-rabbitmq/ (though don't need alternate
routing, nor is that example in python).
For example, I see: https://beam.apache.org/blog/
2017/08/28/timely-processing.html
and tickets like: https://issues.apache.org/jira/browse/BEAM-4594

FYI: the reference DirectRunner implementation of the Python user state and
timers API is out for review: https://github.com/apache/beam/pull/6304

Hey Austin,
This API is not yet implemented in the Python SDK. I am working on this
feature: the next step from my end is to finish a reference implementation
in the local DirectRunner. As you note, the doc at
https://s.apache.org/beam-python-user-state-and-timers describes the design.

Hey Austin,
This API is not yet implemented in the Python SDK. I am working on this
feature: the next step from my end is to finish a reference implementation
in the local DirectRunner. As you note, the doc at
https://s.apache.org/beam-python-user-state-and-timers describes the design.
