Attributes

def apply[O : TypeInformation](fun: (T1, T2) => O): DataStream[O]

Completes the join operation with the user function that is executed for windowed groups.

def apply[O : TypeInformation](fun: (T1, T2, Collector[O]) => Unit): DataStream[O]

Completes the join operation with the user function that is executed for windowed groups.

Completes the join operation with the user function that is executed for windowed groups.

def evictor(newEvictor: Evictor[_ >: TaggedUnion[T1, T2], _ >: W]): WithWindow[W]

Sets the Evictor that should be used to evict elements from a window before emission.

Sets the Evictor that should be used to evict elements from a window before emission.

Note: When using an evictor window performance will degrade significantly, since pre-aggregation of window results cannot be used.

Attributes

@PublicEvolving
def trigger(newTrigger: Trigger[_ >: TaggedUnion[T1, T2], _ >: W]): WithWindow[W]

Sets the Trigger that should be used to trigger window emission.

Sets the Trigger that should be used to trigger window emission.
