> With the rework of sharedBuffer Flink-9418, the lock & release operation is 
> deal with rocksdb state which is different from the previous version which 
> will read the state of sharedBuffer all to memory, i think we can add a cache 
> or variable in sharedbuffer to cache the LockAble Object to mark the ref 
> change in once process in NFA, this will reduce the count when the events 
> point to the same NodeId.. And flush the result to MapState at the end of 
> process.
