NiFi System Properties
Also available as:

Custom Properties

To configure custom properties for use with NiFi's Expression Language:

  • Create the custom property. Ensure that:

    • Each custom property contains a distinct property value, so that it is not overridden by existing environment properties, system properties, or FlowFile attributes.

    • Each node in a clustered environment is configured with the same custom properties.

  • Update with the location of the custom property file(s):



This is a comma-separated list of file location paths for one or more custom property files.

  • Restart your NiFi instance(s) for the updates to be picked up.

Custom properties can also be configured in the NiFi UI.
