大数据计算MaxCompute上有没有什么参数，可以限制在这个sql任务运行过程？

大数据计算MaxCompute上有没有什么参数，可以限制在这个sql任务运行过程中，最多running多少个Instance这样的？比如我设置为1000，虽然整个join 有2000个task,但是最多只能同时运行1000个这样的？

MaxCompute有参数可以设置抢占资源吗？同时发起批量SQL，CU是怎么分配的？

MaxCompute计算资源分为两种模式，按量付费和包年包月，两种计费方式相互独立。按量付费可以理解为公共计算资源池，包年包月为独享计算资源池。包年包月对资源设置可以参考以下文章： 1.包年包月资源分时设置：https://developer.aliyun.com/article/768984 2.包年包月项目作业使用按量付费资源：https://help.aliyun.com/docume....
