> Currently, trying to restore state, which was previously configured without 
> TTL, using TTL enabled descriptor or vice versa will lead to compatibility 
> failure and StateMigrationException.
> In some scenario, user may enable state ttl and restore from old state which 
> was previously configured without TTL;  or vice versa.
> It would be useful for users if we support state compatibility between 
> enabling TTL and disabling TTL.
