Hi, I am having a difficult time distinguishing the difference between RuntimeContext state and global state when using a ProcessWindowFunction.
A ProcessWindowFunction has three access different kinds of state. 1. RuntimeContext state. 2. ProcessWindowFunction.Context global state 3. ProcessWindowFunction.Context window state. It's clear to me that the window state belongs to a window, the lines seemed a bit blurred between RuntimeContext state and ProcessWindowFunction.Context global state. Can somebody please elaborate on the differences, and when I should use global state vs runtime context state? Thank you.
