There are no two watermarks for an operator. What I want to say is
"watermark metrics".

Hi Guowei,
Thanks for your response.
What I understand from you, one operator has two watermarks? If so, one
operator's output watermark would be an input watermark of the next
operator? Does it sounds redundant?
Or do you mean the Web UI only show the input watermarks of every operator,
but
Hi, Cam,
I think you might want to know why the web page does not show the watermark
of the source.
Currently, the web only shows the "input" watermark. The source only
outputs the watermark so the web shows you that there is "No Watermark".
Actually Flink has "output" watermark metrics. I think
Hi Till,
Thanks for your response.
Our sources are S3 and Kinesis. We have run several tests, and we are able
to take savepoint/checkpoint, but only when S3 complete reading. And at
that point, our pipeline has watermarks for other operators, but not the
source operator. We are not running
Hi Cam,
could you share a bit more details about your job (e.g. which sources are
you using, what are your settings, etc.). Ideally you can provide a minimal
example in order to better understand the program.

Hello Flink expert,
We have a pipeline that read both bounded and unbounded sources and our
understanding is that when the bounded sources complete they should get a
watermark of +inf and then we should be able to take a savepoint and safely
restart the pipeline. However, we have source that
