Thank you Max. Is there a reference code somewhere to implement checkpointing
for BoundedReadFromUnboundedSource ? I couldn’t quiet figure out where to get
restored checkpointMark. It appears to be specific to runner implementations.

Hello All,
Any idea how to debug this and find out which stage, which DoFn or which
side input is causing the problem?
Do I need to override OnTimer with every DoFn to avoid this problem?
I thought that some uncaught exceptions were causing this and added various
checks and exception handling in
Probably you should apply the Partition[1] transform on the output
PCollection of your read. Note though that the exact parallelization is
runner dependent (for example, runner might autoscale up resulting in more
writers).
Did you run into issues when just reading from Kafka and writing to
Hi Mani,
Just to let you know I think it would make sense to either
(1) implement checkpointing for BoundedReadFromUnboundedSource
or
(2) throw an error in case of a provided checkpoint mark
Like you pointed out, ignoring it like we currently do, does not seem
like a feasible solution.
