> When using the Wait processor, the use of a connection prioritizer (FIFO for instance) on the wait relationship should be recommended in the processor documentation. When having tens of thousands of flow files in the wait relationship, not using a prioritizer could lead to flow files not being released when signal is notified and generate expired flow files.
