Yes, but I was talking about the point at which a new workflow is created. If my transaction completes but DBOS disappears before the necessary workflows are created, I'll have a problem.
Taking my trial example, the onboarding workflow won't have been created and then perhaps the account will continue to run indefinitely, free of charge to the user.
Looking at the trial example, the way I would solve it is that when the user clicks "start trial", that starts a small synchronous workflow that first creates a database entry, then enqueues the onboarding workflow, then returns. DBOS workflows are fast enough to use interactively for critical tasks like this.
Yes, something like that is needed, we're working on building a good interface for it.
> transactional enqueueing
But it is safe as long as it's done inside a DBOS workflow. If the connection is lost (process crashes, etc.) after the transaction but before the child is enqueued, the workflow will recover from the last completed step (the transaction) and then proceed to enqueue the child. That's part of the power of workflows--they provide atomicity across transactions.
