static SlidingWindowPolicy |
SlidingWindowPolicy.slidingWinPolicy(long windowSize,
long slideBy)
Returns the definition of a sliding window of length
windowSize that slides by slideBy . |
SlidingWindowPolicy |
SlidingWindowPolicy.toTumblingByFrame()
Converts this definition to one defining a tumbling window of the
same length as this definition's frame.
|
static SlidingWindowPolicy |
SlidingWindowPolicy.tumblingWinPolicy(long windowSize)
Returns the definition of a tumbling window of length
windowSize . |
SlidingWindowPolicy |
SlidingWindowPolicy.withOffset(long offset)
Returns a new window definition where all the frames are shifted by the
given offset.

static <K,A> SupplierEx<Processor> |
Processors.accumulateByFrameP(List<FunctionEx<?,? extends K>> keyFns,
List<ToLongFunctionEx<?>> timestampFns,
TimestampKind timestampKind,
SlidingWindowPolicy winPolicy,
AggregateOperation<A,?> aggrOp)
Returns a supplier of processors for the first-stage vertex in a
two-stage sliding window aggregation setup (see the
class Javadoc for an explanation of aggregation stages). |
static <K,A,R,OUT> |
Processors.aggregateToSlidingWindowP(List<FunctionEx<?,? extends K>> keyFns,
List<ToLongFunctionEx<?>> timestampFns,
TimestampKind timestampKind,
SlidingWindowPolicy winPolicy,
long earlyResultsPeriod,
AggregateOperation<A,? extends R> aggrOp,
KeyedWindowResultFunction<? super K,? super R,? extends OUT> mapToOutputFn)
Returns a supplier of processors for a vertex that aggregates events
into a sliding window in a single stage (see the
class Javadoc for an explanation of aggregation stages). |
static <K,A,R,OUT> |
Processors.combineToSlidingWindowP(SlidingWindowPolicy winPolicy,
AggregateOperation<A,? extends R> aggrOp,
KeyedWindowResultFunction<? super K,? super R,? extends OUT> mapToOutputFn)
Returns a supplier of processors for the second-stage vertex in a
two-stage sliding window aggregation setup (see the
class Javadoc for an explanation of aggregation stages). |
