Launching your Triggers
At the end of the file containing your triggers, you need to start the trigger engine itself.
This can be done through three different commands.
Start is used to start your triggers running on live data.
Backfill is used to back-fill a region of time.
Interactive takes command-line parameters to let users control how the command is run, and is usually used if you want to turn your trigger into a service that runs in the background.
