Hi Garvit,

If you don't mind to take a look at the source code, I would suggest you to 
have a look at the "StreamTwoInputProcessor#processInput()" in 
StreamTwoInputProcessor.java. Your customer function will be called via here, 
the "CoFlatMapFunction#flatMap1()" will be called via 
streamOperator.processElement1(record);", "CoFlatMapFunction#flatMap2()" will 
be called via streamOperator.processElement2(record);". You could follow the 
calling chain to find more detail if you want.


Best, Sihua

Hi Garvit,

I think you don't need to lock it, they are executed in the same thread sync.

Hi,

Let's consider, I have two keyed streams one for rules and another for data and 
I have created a connected stream.

I am maintaining a managed keyed state (ValueState), rules stream will keep 
updating the state and data stream will keep reading from it.

Do I need to take a lock explicitly while updating the state or not?

I need to understand. 

Please let me know.

Thanks,
