Quantum adapter

Copy Markdown View Source

Quantum owns clock-based triggering. Kathikon owns durable work.

Setup

# mix.exs
{:kathikon, "~> 0.2.1"},
{:quantum, "~> 3.5"}
defmodule MyApp.KathikonScheduler do
  use Quantum, otp_app: :my_app
end
config :kathikon,
  scheduler: Kathikon.Scheduler.Quantum,
  quantum_scheduler: MyApp.KathikonScheduler

When Quantum fires, the adapter enqueues a normal Kathikon job via Kathikon.insert/3.

What Quantum does not own

  • Job storage, retries, history, dead-letter, batches, reporting

Without Quantum

When Quantum is not installed, Kathikon.Scheduler.schedule/3 with a :cron option returns {:error, :quantum_not_available} if the Quantum adapter is configured.
