I agree with Robert.

@Chesnay: The problem has probably already existed in Flink 1.10 and before
because we cannot run jobs with eager execution calls from the web ui. I
agree with Robert that we can/should improve our documentation in this
regard, though.

@Thomas:
1. I will update the release notes to add a short section describing that
one needs to configure the JobManager memory.
2. Concerning the performance regression we should look into it. I believe
Zhijiang is very eager to learn more about your exact setup to further
debug it. Again I agree with Robert to not block the release on it at the
moment.

@Jark: How much of a problem is FLINK-18461? Will it make the CDC feature
completely unusable or will only make a subset of the use cases to not
work? If it is the latter, then I believe that we can document the
limitations and try to fix it asap. Depending on the remaining testing the
fix might make it into the 1.11.0 or the 1.11.1 release.

Cheers,
Till
