Subject: Re: Watermark behavior when connecting streams
Hi Alexis,
please take a look at AbstractStreamOperator [1] for details how the
watermark is calculate for TwoInputOperator. It uses pretty much the same
approach as for with the single input one (it simply takes a minimum).
For watermark re-assignment, we ignore input watermark unless it's
Long.
Hi everyone,
Based on what I know, a single operator with parallelism > 1 checks the
watermarks from all its streams and uses the smallest one out of the non-idle
streams. My first question is whether watermarks are forwarded as long as a
different watermark strategy is not applied downstream?
