Now, in partial aggregation, if aggregationPct > 40% (hardcoded), abandonedPartialAggregation flag will be set, and more rows will be produced without partial aggregation in partial aggregation operator. We can use config abandonPartialAggregationMinPct here instead of 40%.
abandonPartialAggregationMinPct is 80% in velox, and 90% in gluten, which I think is more reasonable.
Testing with TPCDS q67, the query time went from 109 seconds to 90 seconds.
