### Is your feature request related to a problem or challenge? In https://github.com/apache/arrow-rs/pull/9511 we introduced APIs to answer the question "does this boolean array have any true/false values" faster than `true_count() == 0` and such. We should audit uses in DataFusion where we can apply these APIs. From the arrow PR: - **`datafusion/functions-nested/src/array_has.rs`** — `eq_array.true_count() > 0` → `eq_array.has_true()` - **`datafusion/physical-plan/src/topk/mod.rs`** — `filter.true_count() == 0` check → `!filter.has_true()` - **`datafusion/datasource-parquet/src/metadata.rs`** — `exactness.true_count() == 0` and `combined_mask.true_count() > 0` - **`datafusion/physical-plan/src/joins/nested_loop_join.rs`** — `bitmap.true_count() == 0` checks - **`datafusion/physical-expr-common/src/physical_expr.rs`** — `selection_count == 0` from `selection.true_count()` - **`datafusion/physical-expr/src/expressions/binary.rs`** — short-circuit checks for AND/OR ### Describe the solution you'd like Audit use of true_count() and false_count(). ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
