Work Description: jrmccluskey opened a new pull request, #17667:
URL: https://github.com/apache/beam/pull/17667
Allow explicit returns of nil primaries from TrySplit() RTracker calls in
single-windowed contexts. This allows native streaming IOs to simplify returns
in a self-checkpointing contexts to just residuals, removing any extra checks
on returned primaries beyond existence.

> Key: BEAM-14469
> URL: https://issues.apache.org/jira/browse/BEAM-14469
> Project: Beam
> Issue Type: Improvement
> Components: sdk-go
> Reporter: Jack McCluskey
> Assignee: Jack McCluskey
> Priority: P2
> Time Spent: 2h 40m
> Remaining Estimate: 0h
>
> The TestCheckpointing integration test produces a large number of zero-length
> restrictions on split, leading to extremely verbose logging and errors when
> run on dataflow/with multiple runners.
>
> This is tied to the offsetrange tracker producing zero-length restrictions on
> TrySplit() calls in edge cases. The unintended usage of the tracker in this
> streaming context creates this issue but did reveal that TrySplit() calls
> were not allowing nil primary returns, which could cause issues moving
> forward.
