@Lewis_King , Here's an idea. You can fork the "a" output of the QueryRecord processor and send it to a sequence of processors as shown below: The ReplaceText processor will simply replace the entire contents of the flowfile with the information you want to register in the log. For example: This will produce one row per flow file with the source type ("a") and the timestamp. You can them send these to a MergeRecord to avoid saving to many small log files and them to a PutFile to persist the log. You can process the "b" output in a similar way. Cheers, André
