I think the term *instance of a job* might be misleading. The document uses
*operator instance* or *(user) function instance* but IMO it is not clear what
an *instance of a job* is.
I agree that the previous description wasn't good either, but we might try
to come up with something better.
What about "Flink executes a program in parallel by splitting it into
subtasks and scheduling these subtasks to processing slots."?
