Matthias Pohl commented on FLINK-31593:
---------------------------------------
Thanks [~roman].

It should be possible to restore from such a checkpoint (given all the files
are present) even with changelog disabled.
{quote}
With this statement, you're saying that eventually, the test data generation
should succeed because of the non-determinism?! Isn't that an issue users could
face as well?
{quote}
Alternatively, we can just generate the checkpoints with changelog (or
materialization) disabled.

Based on this statement, I'd assume that we should disable changelog behavior
for this test to ensure determinism and a successful test run from the start.
I'm just wondering whether that's going against the intent of this test.
