gortiz opened a new pull request, #18657:
URL: https://github.com/apache/pinot/pull/18657
## Description
`BOOLAND` / `BOOLOR` declare a `BOOLEAN` return type but override their
intermediate result type to `INTEGER`. This change aligns the intermediate
result
type with the function's `BOOLEAN` type for consistency.
## Why it is non-breaking
- `ColumnDataType.BOOLEAN` is stored and serialized as `INT`, so the
multi-stage
intermediate exchange is byte-identical to `INTEGER`.
- The merge stage builds the aggregate call with an `ANY` operand type
checker
(`PinotAggregateExchangeNodeInsertRule`), so Calcite operand validation is
unaffected.
- The single-stage (v1) engine derives the intermediate type from
`AggregationFunction.getIntermediateResultColumnType()` (still `INT`) and
is
unaffected.
Verified against the multi-stage resource query tests
(`ResourceBasedQueriesTest`):
identical results before and after (no behavior change).
