chenhao7253886 commented on issue #831: Powerful Improve: parallel scan exec instance URL: https://github.com/apache/incubator-doris/issues/831#issuecomment-477911442 Now we have support parallel execution for query without join, you can set mt_dop to decide start how many threads for one fragment in one host, so i think you need't support this config and i will support parallel join by partiton join later, and your SQL does't contain GroupBy all, if you query contains Groupby , the computing power of AggregateNode will be matched with the computing power of ScanNode. I wonder if I understand all your ideas.
