Hi all, to anyone that has experience with/knowledge of Global Windows. I am processing an unbounded stream keyed by a unique non-reoccurring value. A new Global window is created for each new key the app encounters and once complete I am cleaning up any state and removing any elements processed by the window. I understand that this window remains open indefinitely, and that the window metadata remains, is this correct? Is it possible to clear the window metadata of a global window, and if not, will this result in unbounded state growth? Any help on this would be appreciated - Thanks.
