Is there a way I can leverage OperatorState (instead of KeyState) to solve my
issue?

Hi,
Data is partitioned by key across machines and state is kept per key. It is
not possible to interact with two keys at the same time.

In other words, while using the Flink streaming APIs, is it possible to take a
decision on emitting a particular key based on the state of some other key
present in the same window?
Thanks!

Task 1: I implemented it using a custom Trigger (see attached file). Looks like it is doing what I want it to. I copied the code from EventTimeTrigger.java and overwrote the onElement method. Task 2: I will need to maintain the state (this will be the LRU cache) for multiple keys in the same data
How would you start implementing it? Where are you stuck?
Did you already try to implement this?

Hi
I am a CS PhD student at UMN Twin Cities. I am trying to use Flink for
implementing some very specific use-cases: (They may not seem relevant but I
need to implement them or I at least need to know if it is possible to
implement them in Flink)

1. Data stream is of the form
