Hello, I am struggling to find suitable APIs to process multiple data frames in parallel. My requirement is the following- I have 10s of distinct spark data frames. A certain set of operations must be performed on each DF ( treating each as a single partition), and some results must be returned from each processing. Ex: Apply func1, func2, func3 to DF1, DF2 and DF3, return list1, list2 and list3 from each. So, in theory, func1, func2 and func3 can be run in parallel. Wondering if there is any pyspark pattern I can follow. Thanks ! ... View more
