> 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
> Fix For: 2.40.0
>
> Time Spent: 3h 50m
> 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.
