Where is the state stored? In my own pg instance? Or is it stored somewhere in the cloud? Also, a small sample code snippet would be helpful.

The state can be stored in any Postgres instance, either locally or in any cloud.

For code, here's the bare minimum code example for a workflow:

  class Example {
    @DBOS.step()
    static async step_one() {
      ...
    }

    @DBOS.step()
    static async step_two() {
      ...
    }

    @DBOS.workflow()
    static async workflow() {
      await Example.step_one()
      await Example.step_two()
    }
  }

The steps can be any TypeScript function.

Then we have a bunch more examples in our docs: https://docs.dbos.dev/.

Or if you want to try it yourself download a template:

    npx @dbos-inc/create

    Are there any constraints around which functions can be turned into steps? I assume their state (arguments?) need to be serializable?

    Also, what happens with versioning? What if I want to deploy new code?
