Martijn Visser closed FLINK-34089.
----------------------------------
Resolution: Won't Fix
If users want to remove a topic from their job, they should change their
savepoint file. Just removing an input topic has implications on your pipeline,
and users shouldn't just do that.
If users have a requirement to (dynamically) add or remove Kafka topics, they
should use the solution that has been brought forward with

> Project: Flink
> Issue Type: Bug
> Components: Connectors / Kafka
> Affects Versions: kafka-3.0.2
> Reporter: tanjialiang
> Priority: Major
> Labels: pull-request-available

> When we unsubscribe a topic and still restore from the old state, the job
> will still read data from the unsubscribed topic. I think we should check if
> that the subscribed topic partitions match the assigned partitions, and throw
> an error so the user can handle it.
