results: a local or instance variable that is accessed by a task’s business logic Operator state is scoped to an operator task, i.e. records processed by the same parallel task have access to the same state It cannot be accessed by other parallel tasks of the same or different operators Keyed state is scoped to a key defined in the operator’s input records • Flink maintains one state instance per key value key to the operator task that maintains the state for this key • State access is automatically scoped to the key of the current record so that all records with the same key access the same state State
