Python 提供了很多内置的工具函数(Built-in Functions),在最新的 Python 3 官方文档中,它列出了 69 个。 大部分函数是我们经常使用的,例如 print()、open() 与 dir(),而有一些函数虽然不常用,但它们在某些场景下,却能发挥出不一般的作用。内置函数们能够被“提拔”出来,这就意味着它们皆有独到之处,有用武...

*rxExecBy() - to partition an input data source and execute user function on each partition in parallel. If the input data source is already partitioned, the function will skip the partitioning step and directly trigger computation for user function on partitions. ...
Allows the distributed execution of an arbitrary R function in parallel, across nodes (computers) or cores of a “compute context”, such as a cluster. For example, you could use the function to execute multiple instances of a model concurrently. When us
