@Balakrishnan Ramasamy The NiFi expression language allows users to dynamically retrieve values from FlowFile Attributes, environment variables, JVM properties, or a variable registry file. Only properties that are marked as supporting expression language can be passed value dynamically. Floating your cursor over the little question mark next to any property will tell you if it support expression language or not. For sensitive property fields, the value entered is encrypted upon hitting OK. It is then stored in the encrypted format in the flow.xml.gz file. It does not support the expression language. Please accept my answer if you feel i have addressed your question. Thank you, Matt ... View more
