The State Processor API goes a bit in the direction you asking about, by making it possible to query savepoints.

That's not possible, but you might be interested in queryable state:

I'm afraid that doesn't exist, and it probably never will because
usually RocksDB is not a distributed system so writing to it from a
parallel stream processing application would most likely not work well.
