Hi Nick, Users almost always like the idea of new features, whatever they are. But that doesn't mean that the feature would necessarily work well or be necessary. If you still want to pursue this, then I suggest gathering a set of use-cases that can't be addressed through the means we discussed here previously. So, something that can't effectively be addressed through using the pause and resume API. Then come up with a concrete proposal that addresses all the questions we have, including about starvation, incremental fetch requests, and so on. This could be a lot of work. If you're looking for a way to make more contributions, I'd recommend getting started with something easier. best, Colin > Cheers, > -- > Nick > > > >
