In general, yes. This affects portable runners other than Dataflow. There's a
workaround for Flink by starting up an expansion service with the
'use_deprecated_read' experiment.

> To execute unbounded Splittable DoFn over fnapi in streaming mode properly,
> portable runners should issue split(ProcessBundleSplitRequest with
> fraction_of_remainder > 0) or simply checkpoint(ProcessBundleSplitRequest
> with fraction_of_remainder == 0) to SDK regularly to make current bundle
> finished processing instead of running forever.
