-Re: Round robin with backoff

I'm guessing that was just a slip with ROUND_ROBIN_BACKOFF => RANDOM.
Rahul: Both RANDOM and ROUND_ROBIN now have backoff semantics in them.
So RANDOM_BACKOFF became RANDOM and ROUND_ROBIN_BACKOFF became
ROUND_ROBIN. It as processors fail, they will be temporarily blacklisted
and the random/round_robin semantics will be carried out on the
remaining sinks as one would expect.

It looks like there is a constant with this type defined in code, but it is not used anywhere. The code seemed to indicate that the below should achieve a backoff for Round Robin though there is not documentation about the processor.backoff parameter. Is the below the right way to perform a round robin with backoff?
