This can be very powerful and useful, but it can also backfire if you base some of your logic on this behaviour, and in the future, you move to another active job backend, or if you simply move Solid Queue to its own database, and suddenly the behaviour changes under you. Because this can be quite tricky and many people shouldn't need to worry about it, by default Solid Queue is configured in a different database as the main app, **job enqueuing is deferred until any ongoing transaction is committed** thanks to Active Job's built-in capability to do this. This means that even if you run Solid Queue in the same DB as your app, you won't be taking advantage of this transactional integrity.
