> When we set a StateTTLConfig to StateDescriptor, then when a record has been expired, it is deleted from the StateBackend.
> I want suggest a new feature, that we can get the expiring results as side output, to process them and not just delete them.
> For example, if we have a ListState that have a TTL enabled, we can get the expiring records in the list as side-output.
> What do you think?
