> Currently the TaskInstance.checkCaughtUp() logic has a bug that if there is 
> no incoming messages for a partition, it will not mark the ssp to be caught 
> up. Instead, it should mark ssp to be caught up if the starting offset is 
> already the upcoming offset for a ssp, meaning it has consumed all the 
> messages in this partition and waiting for the future incoming messages. This 
> indicates the ssp is fully caught up.
