Apache Flink - Side output time semantics for DataStream

[M Singh]

Hi:

I wanted to find out what is the timestamp associated with the elements of a stream side output with different stream time characteristics.

Thanks

Hi,

I'm not sure what you exactly mean. Could you describe more about your requirements?

Hi Biao:  Thanks for your response.

My question is that if i have streaming application and with timestamp assigned to the elements, and in one of the process functions I have side output, then there are two situations possible:

1. The side output is the same type as main stream.

2. The side output is different from the main stream.

In both the above scenarios - what is the timestamp associated with the elements in side output stream?  Is it the same as the element that produced the side output ?  

Thanks
