Just echoing @quinnj response. I have a rule of thumb:

- If it takes less than `3s`, handle it through `http`
- Otherwise, schedule a worker

Probably can do this on heroku with a `web` and `worker` dyno (it would be free if you got it working)

_(the grain of salt is i’ve only hosted using heroku with rails.)_
