Additionally, a background task is normally an independent set of logic that should be handled separately, with its own resources (e.g. its own database connection).

So, this way you will probably have cleaner code.

Además, una tarea en background es normalmente un conjunto independiente de lógica que debería manejarse por separado, con sus propios recursos (por ejemplo, su propia conexión a base de datos).

De esta manera probablemente tendrás un código más limpio.
