“轻重”之策可以“御天下”。古代国家之间的经济竞争激烈，“轻重”理论主张当政者应奖励优待外来商人，通过内外政令吸引其他国家的财货、资金和人民为我所用，同时守住本国的关键物资不外流，并运用货币和价格工具引导他国形成对本国的依附性经济结构，最终赢得“天下轻我重”的优势地位。。zoom对此有专业解读

For memory-intensive aggregations or sorting scenarios, users can use the settings max_bytes_before_external_group_by and max_bytes_before_external_sort respectively. The former of these is discussed extensively here. In summary, this ensures any aggregations can "spill" out to disk if a memory threshold is exceeded. This will impact query performance but will help ensure queries do not run out of memory. The latter sorting setting helps address similar issues with memory-intensive sorts. This can be particularly important in distributed environments where a coordinating node receives sorted responses from child shards. In this case, the coordinating server can be asked to sort a dataset larger than its available memory. With max_bytes_before_external_sort, sorting can be allowed to spill over to disk. This setting is also helpful for cases where the user has an ORDER BY after a GROUP BY with a LIMIT, especially in cases where the query is distributed.，详情可参考比特浏览器
