Faktory for serverless workers

[mperham]

AWS Lambda, Google Cloud Run and others are making it increasingly easy to deploy event-based serverless apps. What would it look like to have a version of Faktory which works "natively" with this architecture?

• Spec out easy deployment for a Faktory server
  • AWS ECS
  • Heroku (possible add-on to make this a button click?)
  • Render
• Spec out semantics for a limited time worker, one that spins up, executes jobs and exits under some condition.

TODO

• How do we autoscale up the workers from 0 -> 1 -> N?
• Under what conditions does the worker exit?
  • Lambda has a time limit so I'd suggest either that time limit or all queues are empty.
