Labels: pull-request-available (was: )
> Improve BIN BY test coverage for DST and bin alignment
> ------------------------------------------------------
>
> Key: SPARK-58139
> URL: https://issues.apache.org/jira/browse/SPARK-58139
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 5.0.0
> Reporter: Nikolina Vraneš
> Priority: Major
> Labels: pull-request-available
>
> Add BIN BY execution test coverage for day-time interval edge cases that
> share the time_bucket bin-boundary arithmetic:
> - DST fall-back: a 1-day LTZ bin across the 2024-11-03 fall-back (the 25-hour
> day gets a larger ratio share than an adjacent 24-hour day), and a compound
> 2-day width across the same transition.
> - Sub-day bin in a non-UTC session, exercising the UTC-arithmetic path
> (distinct from the civil-time path the multi-day tests use).
> - ALIGN TO an origin later than the range, exercising the negative step-back
> in the bin-boundary arithmetic.
> Test-only. Sub-task of SPARK-57133.
