[fix](cost model) scale group-by-less global agg cost by BE number when partitioned by foxtail463 · Pull Request #66354 · apache/doris

foxtail463 · 2026-08-01T17:20:40Z

Problem Summary:
A scalar count(distinct) runs its global aggregate hash-shuffled by the distinct
key (non-empty partitionExpressions), i.e. in parallel across BEs. But the cost
model set the parallelism factor from group-by keys alone, so with no group by it
used factor = 1, costing the aggregate as single-point. This overestimated the
parallel plan and made CBO reject it.

Solution:
Treat a global aggregate as partitioned when it has group by keys or non-empty
partitionExpressions, and scale its cost by beNumber accordingly.
