How to throttle event stream using RX?

by

Okay,

you have 3 scenarios here:

1) I would like to get one value of the event stream every second.
means: that if it produces more events per second, you will get a always bigger buffer.

observableStream.Throttle(timeSpan)

2) I would like to get the latest event, that was produced before the second happens
means: other events get dropped.

observableStream.Sample(TimeSpan.FromSeconds(1))

3) you would like to get all events, that happened in the last second. and that every second

observableStream.BufferWithTime(timeSpan)

4) you want to select what happens in between the second with all the values, till the second has passed, and your result is returned

observableStream.CombineLatest(Observable.Interval(1000), selectorOnEachEvent)
