Also could you explain the difference between trigger.start() and trigger.start_remotely()

Start will start the trigger process (the one "watching the changes") locally (this makes sense for debugging etc.)
start_remotely will launch the trigger process on the "services" where it should live forever 🙂

Okay so when I add trigger_on_tags, the repetition issue is resolved.

Nice!

This problem occurs when I'm scheduling a task. Copies of the task keep being put on the queue even though the trigger only fired once.

Hmm I think a bit lost here (and I have a feeling there is some hidden bug somewhere that I'd like us to fix)
How exactly do I make it trigger twice on the same Dataset?
