StageWithKeyAndWindow.aggregate3(StreamStageWithKey<T1,? extends K> stage1,
StreamStageWithKey<T2,? extends K> stage2,
AggregateOperation3<? super T,? super T1,? super T2,?,? extends R> aggrOp)
Attaches a stage that performs the given cogroup-and-aggregate operation
over the items from this stage as well as
stage1 and stage2 you supply. |
StreamStage<KeyedWindowResult<K,ItemsByTag>> |
WindowGroupAggregateBuilder.build()
Creates and returns a pipeline stage that performs a windowed
cogroup-and-aggregate operation on the stages registered with this
builder object.
|
<R> StreamStage<KeyedWindowResult<K,R>> |
WindowGroupAggregateBuilder1.build(AggregateOperation<?,? extends R> aggrOp)
Creates and returns a pipeline stage that performs a windowed
cogroup-and-aggregate of the pipeline stages registered with this builder object.
|
default StreamStage<KeyedWindowResult<K,T>> |
StageWithKeyAndWindow.distinct()
Attaches a stage that passes through just the items that are distinct
within their window according to the grouping key (no two items emitted
for a window map to the same key).
