Custom metrics in Watermark Assigner

[Oleksandr Nitavskyi]

Hello guys,

 

In our custom AssignerWithPunctuatedWatermarks we want to have custom metrics. Unfortunately operator’s wrapping this assigner interface is hidden from user API. What do you think if we add some optional api in order to let user possibility to register custom metrics in the watermark assigner?

This feature would increase introspectability of the custom watermark logic, which sometime is hard to debug.

 

Kind regards

Oleksandr

Hi Oleksandr,

It sounds like a good idea to make a lot of internal information more transparent. But it would be better if you could be more specific.

Thanks, vino.
