  and aggregations. This is managed by `query.max-hash-partition-count`
  (renamed from `query.hash-partition-count`) and `query.min-hash-partition-count`
  configuration toggles. It's also possible to set minimum number of rows and
  minimum data size per task using `optimizer.min-input-rows-per-task` and
  `optimizer.min-input-size-per-task` config properties. ({issue}`15489`)
