to their respective adapters. Active Job comes pre-configured with an inline
runner that executes jobs right away.

Jobs often need to take Active Record objects as arguments. Active Job passes
object references as URIs (uniform resource identifiers) instead of marshaling
the object itself. The new
[
Global ID
](
https://github.com/rails/globalid
)
library builds URIs and looks up the objects they reference. Passing Active
Record objects as job arguments "just works:" Active Job passes a reference to
the object, then looks up the object from its reference.
Record objects as job arguments just works by using Global ID internally.
For example, if
`trashable`
is an AR this job runs just fine
```
ruby
class
TrashableCleanupJob
<
ActiveJob
::
Base
def
perform
(
trashable
,
depth
)
trashable
.
cleanup
(
depth
)
end
end
```
with no serialization involved.
