getChan opened a new pull request, #20321: URL: https://github.com/apache/datafusion/pull/20321
## Summary - implement `cardinality_effect` for `WindowAggExec` - implement `cardinality_effect` for `BoundedWindowAggExec` - both return `CardinalityEffect::Equal` ## Why Window operators add output columns while preserving one output row per input row, so their cardinality effect is `Equal`. Fixes #20291 ## Validation - `cargo test -p datafusion-physical-plan window_agg` - `cargo test -p datafusion-physical-plan bounded_window_agg` -- This is an automated message from the Apache Git Service.
