IterCb :Iterator callback,called for every key,value found in maps.

NAAJType is join detail type only used by null-aware AntiLeftOuterSemiJoin.

UpsertCb : Callback to return new element to be inserted into the map It is called while lock is held, therefore it MUST NOT try to access other keys in same map, as it can lead to deadlock since Go sync.RWLock is not reentrant.
