func TriggerAfterAll added in v2.40.0 

func TriggerAfterAll(s beam.Scope)

TriggerAfterAll tests AfterAll trigger. The output pane is fired when all triggers in the subtriggers are ready. In this test, since trigger.AfterCount(int32(5)) won't be ready unless we see 5 elements, trigger.Always() won't fire until we meet that condition. So we fire only once when we see the 5th element.

func TriggerAfterAny added in v2.40.0 

func TriggerAfterAny(s beam.Scope)

TriggerAfterAny tests AfterAny trigger. In this test, trigger.Always() gets ready everytime. So we would expect panes to be fired at every element irrespective of checking for other triggers.

func TriggerAfterEach added in v2.40.0 

func TriggerAfterEach(s beam.Scope)

TriggerAfterEach tests AfterEach trigger. The output pane is fired after each trigger is ready in the order set in subtriggers. In this test, since trigger.AfterCount(int32(3)) is first, first pane is fired after 3 elements, then a pane is fired each for trigger.Always() for element 5.0 and 8.0

func TriggerAfterEndOfWindow added in v2.34.0 

func TriggerAfterEndOfWindow(s beam.Scope)

TriggerAfterEndOfWindow tests the AfterEndOfWindow Trigger. With AfterCount(2) as the early firing trigger and AfterCount(1) as late firing trigger. It fires two times, one with early firing when there are two elements while the third elements waits in. This third element is fired in the late firing.

func TriggerAfterProcessingTime 

func TriggerAfterProcessingTime(s beam.Scope)

TriggerAfterProcessingTime tests the AfterProcessingTime Trigger, it fires output panes once 't' processing time has passed Not yet supported by the flink runner: java.lang.UnsupportedOperationException: Advancing Processing time is not supported by the Flink Runner.

func TriggerAfterSynchronizedProcessingTime added in v2.40.0 

func TriggerAfterSynchronizedProcessingTime(s beam.Scope)

TriggerAfterSynchronizedProcessingTime tests AfterSynchronizedProcessingTime trigger. It fires at the window expiration since the times doesn't synchronize in this test case.

func TriggerAlways 

func TriggerAlways(s beam.Scope)

TriggerAlways tests the Always trigger, it is expected to receive every input value as the output.

func TriggerDefault 

func TriggerDefault(s beam.Scope)

TriggerDefault tests the default trigger which fires the pane after the end of the window

func TriggerElementCount 

func TriggerElementCount(s beam.Scope)

TriggerElementCount tests the ElementCount Trigger, it waits for atleast N elements to be ready to fire an output pane

func TriggerNever added in v2.40.0 

func TriggerNever(s beam.Scope)

TriggerNever tests Never Trigger. It fires at the window expiration.

func TriggerOrFinally added in v2.40.0 

func TriggerOrFinally(s beam.Scope)

TriggerOrFinally tests OrFinally trigger. The main trigger in this test case trigger.Always() is always ready. But the output is produced only when finally trigger is ready. So it is ready at second element in first window and produces two output panes. Similarly, for the second window.

func TriggerRepeat 

func TriggerRepeat(s beam.Scope)

TriggerRepeat tests the repeat trigger. As of now is it is configure to take only one trigger as a subtrigger. In the below test, it is expected to receive three output panes with two elements each.

func ValidateWindowedSideInputs added in v2.35.0 

func ValidateWindowedSideInputs(s beam.Scope)

ValidateWindowedSideInputs checks that side inputs have accurate windowing information when used.

func WindowSums 

func WindowSums(s beam.Scope, sumPerKey func(beam.Scope, beam.PCollection) beam.PCollection)

WindowSums produces a pipeline that generates the numbers of a 3x3 magic square, and configures the pipeline so that PCollection. Sum is a closure to handle summing data over the window, in a few conditions.

func WindowSums_GBK 

func WindowSums_GBK(s beam.Scope)

func WindowSums_Lifted 

func WindowSums_Lifted(s beam.Scope)

Types

type RangeEstimator added in v2.40.0
