Hi Jose,
As far as I know, you should be able to use keyed state on a stream returned by DataStreamUtils.reinterpretAsKeyedStream function. That shouldn’t be the issue here.
Have you looked into the logs for any meaningful exceptions of why the restore failed?
That would be helpful here to understand whether or not this is a bug.
Cheers,
Gordon

Hi,
To avoid reshuffling in my job, I started using
DataStreamUtils.reinterpretAsKeyedStream to avoid having to do another keyBy for the same
key. The BackEndState is RocksDB.
When the job recovers after a failure,
the ProcessFunction after the keyBy restores its Keyed State
correctly, while the Process function
after reinterpretAsKeyedStream does not recover the Keyed
State.
I have checked the data written by the
checkpoints and there is a reference to the sate.
If I change and use keyBy instead
of DataStreamUtils.reinterpretAsKeyedStream the Keyed State is recovered as
expected.
Is
the DataStreamUtils.reinterpretAsKeyedStream function not intended to use Keyed
State?
Thank you.

Jose
