so we have a streaming job where the main work to be done is processing infinite kafka sources. recently, i added a fromCollection (finite) source to simply write some state once upon startup. this all seems to work fine. the finite source operators all finish, while all the infinite source operators continue running with watermarks.
however, the weird thing is that savepointing throws exceptions, and there have been no automatic checkpoints at all while the job has been running for 90+minutes (checkpoint config is unaligned, exactly once every 5m w/ a 1h timeout). is this mixed finity not a supported setup?
