Guewen is talking about the creation, not the execution of jobs. If
you have a big method that creates a few jobs and has an error, the
creation of the jobs is rolled back.

Retrying failed jobs is something else, and it is supported indeed.

Guewen was indeed an answer to that already :)

- transactional job creation
- easy integration of the interface in odoo so for example you can
inspect the jobs in the interface which is nice
- a lot of work has been done already.

A dedicated worker like rabbitmq (so something like celery) is indeed
desirable if you have huge amounts of jobs. For the loads we face
usually the OCA connector + postgres setup works just fine.

See for documentation. The magento connector is
indeed something of a reference implementation, although bear in mind
that it does much more than just a job queue.

It works well to use only the job queue part without the full
e-commerce framework if that's what you need. On the other hand with
celery you have a (nice, mind you) job queue, and you have to start
from there and roll your own stuff.
