We’re used to doing reviews for source code. NiFi flows look different, but when they are part of your application’s code, it’s useful to have a review prior to committing. Here’s what I look for when I’m reviewing a flow.
The NiFi EvaluateJsonPath processor lets you specify a JSON path, which will be applied to the content of a flow file. For most situations that works great, but what if you want to retrieve a value where the property you want to read depends on a flow file attribute? EvaluateJsonPath doesn’t support the expression language on dynamic attributes. Use an ExecuteScript processor instead.
