> "because the entire result set must be produced and transferred to one node
> before the sorting can happen." is incorrect. If there is an "ORDER BY"
> clause in a select block, then first data is sorted locally by each impala
> daemon, then streamed to the coordinator, which merges the sorted result sets.
