Work Description: yifanmai opened a new pull request #14647:
URL: https://github.com/apache/beam/pull/14647
Runners should not use `pack_all_combiners` because it is not a transparent
optimization; it can cause user-visible changes in counters. Runners should use
`pack_combiners` instead, which only runs on stages with annotations.

> translations.pack_combiners optimizer causes breaking change to metrics API
> ---------------------------------------------------------------------------
>
> Key: BEAM-11644
> URL: https://issues.apache.org/jira/browse/BEAM-11644
> Project: Beam
> Issue Type: Bug
> Components: sdk-py-core
> Affects Versions: 2.27.0
> Reporter: Yifan Mai
> Assignee: Robert Bradshaw
> Priority: P1
> Fix For: 2.28.0
>
> Time Spent: 5h 40m
> Remaining Estimate: 0h
>
> The translations.pack_combiners optimizer causes a breaking change in the
> public metrics API. The issue arises because metrics are keyed and queryable
> by step name, and the step name can change after combiner packing. Suppose we
> have a pipeline that looks like `pipeline | CombinePerKey(combinefn_1);
> pipeline | CombinePerKey(combinefn_2)` and both combinefn_1 and combinefn_2
> increment the same counter per input element. Previously, the result would
> have two counters, one each for step combinefn_1 and combinefn_2; both will
> have value num_input_elements. After combiner packing, the result will have
> one counter for Packed[combinefn_1, combinefn] with value 2 *
> num_input_elements.
> Unfortunately there is no easy fix for this because the runner has to somehow
> be aware that a step is a packed step and use the appropriate metrics
> container for the sub-step.
> The short term workaround is to (1) add a note for 2.27 under known issues
> and (2) make this phase opt-in in 2.28.
