> 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.
