A DFM may need to inspect a FlowFile's content at some point in the dataflow to ensure that it is being processed as expected. And if it is not being processed properly, the DFM may need to make adjustments to the dataflow and replay the FlowFile again. The Content tab of the View Details dialog window is where the DFM can do these things. The Content tab shows information about the FlowFile's content, such as its location in the Content Repository and its size. In addition, it is here that the user may click the Download button to download a copy of the FlowFile's content as it existed at this point in the flow. The user may also click the Submit button to replay the FlowFile at this point in the flow. Upon clicking Submit, the FlowFile is sent to the connection feeding the component that produced this processing event.
