Flavio -

I took a look at your code this morning. At a high level this looks more
or less correct. A few comments:

1) Even though this is a demo, you should be aware that if your getGroup
or other methods where you call ³get()² are called from onDataChange etc
you may end up on a deadlock scenario. We are pushing a fix shortly that
will throw an exception if that happens, but just be aware that it can
happen.

2) Also, the new data broker by default does not create parent nodes so
that may cause some confusion when migrating code. That said, we are also
introducing a patch shortly that will allow people to optionally create
parent nodes in the same way that the original databroker service did.
That way the port will be more straight forward. You may need to tweak
this code again shortly.

3) Ultimately I would suggest looking at the toaster example for async
code samples as well as suggestions on how to handle various exceptions
etc.

Hope that helps,

Devin

Hi Devin,

I took a stab at replacing DataBrokerService with DataBroker in ovsdb.

With that, I would like very much to hear from you on whether I got this
right, or if what I¹m doing is
completely off the tracks:

https://git.opendaylight.org/gerrit/#/c/9184/

Could you please take a peek on that (specifically, the changes to
ŒGroup¹ in the OF13Provider.java)
and let me know?

Thanks!
