Review comment:
I am wondering whether this information is really helpful for a user of
Flink. My spontaneous gut feeling is that it could also be logged on debug log
level. This, however, already happens a couple of lines above.
Hence, I guess the first question is whether this is information we want to
expose to every user. If yes, then we should probably change the `LOG.debug`
line above to not log duplicate information on debug log level.
