Job Records In/Out metrics clarification

[Rafi Aroch]

Hi,

Below is the In/Out metrics as they appear in the Flink UI.
I was wondering what are the possible reasons that the "Records sent" of
one operator is different than the "Records received"  of the next one. I
would expect to see the same number...

* We're using Flink 1.5.0 version.

Thanks,
