Hi, Just wondering what is the best practice for my use-case. My flowfiles are json objects and I need to filter/route them using external file (with list of values) - i.e. per flowfile to check if the value of some field (key) X is in the file or not. The only two processors I noticed I can use for that are ScanContent and ReplaceTextWithMapping (which will "replace" a value in identical one). ScanContent seems to be more appropriate since it does not perform a redundant 'Replace' action, but on the other hand it does not have the 'File Refresh Interval' property as the ReplaceTextWithMapping. Hence I'm guessing it continuously refresh the dictionary file (I didn't find relevant information about this issue in the documents), which is also an expensive (and redundant for my use-case) action that can harm the performance of the flow. I tend to use the ReplaceTextWithMapping approach and skip the continuous refreshing of the file, but just wanted to ask around here, to check if there is another best-practice approach and make sure I get things right / didn't miss something. Thanks in advance, Liran ... View more
