Good idea!
Given the fact that we are stabilizing at the moment (and this is
introducing new functionality), I vote to postpone that to after the 0.9
release. That would be two weeks or so, if things go well.
Until then, here are a few thoughts
- Terminate sounds like a very non-graceful killing. What this does is
the opposite, so how about calling it "stop" signal.
- We will need a way to stop streaming jobs and perform a checkpoint
during the stopping. Would be good to bear this in mind. Can we add this as
part of this pull request?

> Currently, streaming jobs can only be stopped using "cancel" command, what is
> a "hard" stop with no clean shutdown.
> The new introduced "terminate" signal, will only affect streaming source
> tasks such that the sources can stop emitting data and terminate cleanly,
> resulting in a clean termination of the whole streaming job.
