Hi [~trohrmann], I open a [pull
request|https://github.com/apache/flink/pull/17443] to resolve this, but there
are still some unit test that I think need to be complete. Can you take a
glance over this PR and give me some guidance on the unit test ?

> Savepoint can take much longer time to perform than checkpoint, especially
> with incremental checkpoint enabled. This leads to a couple of troubles:
> * For our job, we currently have to set the checkpoint timeout much large
> than necessary, otherwise we would be unable to perform savepoint.
> * During rush hour, our cluster would encounter high rate of checkpoint
> timeout due to backpressure, however we're unable to migrate to a larger
> configuration, because savepoint also timeout.
> In my opinion, the timeout for savepoint should be configurable separately,
> both in the config file and as parameter to the savepoint command.
