Azure Data Lakes (Hadoop) 中的优先级和并行值意味着什么?

What do priority and parallelism value mean in Azure Data Lakes (Hadoop)?

换句话说,并行度值为 5 和优先级值为 1000 是什么意思?

它们会影响您的工作方式和时间 运行。优先级决定了一个作业可以运行相对于其他排队作业的顺序,并行性设置了为它启动了多少个并行进程(更多意味着它运行s更快但成本更高)

优先级

默认值为 1000。

平行度

Max number of compute processes that can happen at the same time. Increasing this number can improve performance but can also increase cost.
