Thanks Joe, so you mean for example, if I set one processor to run only on primary node in the cluster and there're 100 FlowFiles in the incoming queue of the processor waiting to be processed by this processor, and the processor suddenly goes down and then another node is elected as the primary node, those 100 FlowFiles will be kept locally in the node that went down and will continue to be processed by the node when it goes back online, these FlowFiles will not be available to the new primary node and other nodes, am I correct?
