Hi all, Imagine I have a default parallelism of 16 and I do something like
stream.keyBy("something").flatMap()
Now let's imagine I have less than 16 keys, maybe 8.
How many parallel executions of the flatMap function will I get? 8 because
I have 8 keys, or 16 because I have default parallelism at 16?
(and I will have follow up questions depending on the answer I suspect ;))
Thanks,
