----------------------------------
Assignee: Michael Moser (was: Aldrin Piri)
> ControlRate processor does not accurately control the rate
> ----------------------------------------------------------
>
> Key: NIFI-627
> URL: https://issues.apache.org/jira/browse/NIFI-627
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Affects Versions: 0.1.0
> Reporter: Michael Moser
> Assignee: Michael Moser
> Priority: Minor
> Fix For: 0.2.0
>
>
> Set a ControlRate processor to something like 5 KB per 1 sec. Generate flow
> files that are about 300 KB in size and feed a bunch to this processor. This
> should allow about 5 files through per 5 minutes. But it allows a lot more
> data through than it should. The difference seems to get worse with really
> low Time Duration values. And people tend to think in number of bytes per
> second so the temptation to set Time Duration to 1 sec is great.
> Also, if ControlRate has multiple input queues, it seems to output even more
> data than it should.
> This seems to be caused by the code at the beginning of ControlRate
> onTrigger(). Under some conditions when the number of files that are allowed
> through per Time Duration is less than 1, the Throttle is being removed from
> the throttleMap while it actually still should be in use.
