Hi,

I was working on a streaming application last week and I got stuck in a
situation where I got the same time based window many times.
I expect that I made a mistake in creating the watermarks in relation to
the data I have and the watermark generating code.

Writing the events to the console (for debugging) is easy, yet I have not
been able to write the watermarks to my console.

My question is very simple: How do I log the watermarks in the console so I
can see the data and understand my mistake.

I would also like to know "where do the watermarks live" in relation to the
actual data.

Thanks.

Niels Basjes
