Work Description: youngoli opened a new pull request #13070:
URL: https://github.com/apache/beam/pull/13070
Adjust Go SDF splitting and execution code so that splits take exploded
windows into consideration and perform splits at window boundaries. Also
required adjusting various split logic to accept multiple residuals and
primaries from splits.
The changes to the splitting logic itself are in exec/sdf.go, and the tests
are in the corresponding test file. The rest of the changes are mostly related
to adjusting other code to handle the change from single primaries and
restrictions to multiple primaries and restrictions, or just small bugfixes
(like offsetrange.RTracker.GetProgress).

>
> When splitting an element that's being processed on multiple windows,
> currently the element gets split based on the current progress of the current
> element+window pair, and the primary and residual both contain all windows
> from the original. This is incorrect as certain windows in the residual have
> already been processed.
> The correct way to perform this split is to put the element + all fully
> processed windows in the primary, the element + all fully unprocessed windows
> in the residual, and then only split the element at the current element +
> window pair.
> This fix should already be in Java and Python, so those can be referenced.
