Hi
I have some odd behaviour with the reactive nodes… may be a bug, may just be my poor understanding.
I want to parse a large CSV file but I don’t want it to interrupt my drawing.
I thought a perfect job for the reactive nodes to do in a background thread.
V1: when I set it up like this and click send I get a momentary freeze in framerate and my drawing stutters. I appear to get the result the next frame (although it’s a looong frame) which makes me think it’s happening on my main loop.
V2: when I add a delay to the event of zero seconds I get much better behaviour. I lose some FPS (but not a dramatic amount) for about 10 frames then the event returns. Which is what I’d expect from a background task.
the reactive nodes try to create as less threads as possible. so the ToObservable does not create a new thread by default. there is a parameter internally to set the scheduler but we have not yet published it.
for now you need to start a new thread with Interval or Timer, both create a new thread.
Ah wait, is there a way to pass in a dynamic argument (other than the time) with observables generated by Interval or Timer? I think I need to pass in the path or stream of my CSV file in order to get it processed.
