Force Processor to PULL flowfiles from Queues/Replationship

Explorer

Hi,

I have the following data flow and the WW processor is not pulling data from the queue , how can i force the WW processor to pull flowfiles from the queue between it and its predecessor processor (XX processor).

Re: Force Processor to PULL flowfiles from Queues/Replationship

The queue before the WW processor shows 0 flow files queued so there is nothing to pull.

Also, since the queue between XX and ZZ is showing that it is full, this means back-pressure is engaged and the XX processor will no longer execute until space is available in that queue, which then has the side-effect that XX also can't put more flow files into the queue before WW.
