Hi, Is there a way to configure the key group cardinality for an operator substate when taking a savepoint?

you have to set this before you start the job by setting the max_parallelism of the pipeline

Ah, I didn’t know it was bound to that property. But thinking of it, it makes sense now. But now that it has already been set for my job, I’m kind of stuck with it right? (Unless I play with the state processing API to re shuffle my save point)

yes, you cannot change this normally for existing checkpoints

Thank you for your prompt response!
