# PostProcessingDefaultParameters

The name of a configuration section that defines default values for parameters for your Lua post-processing scripts.

This parameter specifies the name of a section in the NiFi Ingest configuration file that contains default values for parameters to use in your post-processing scripts. You must create this section and add a list of parameter value pairs for the default values.

When NiFi Ingest calls the post-processing script, if you do not add parameters programatically, NiFi Ingest adds these default parameters to the Lua user parameters object used by the Lua post-processor. The Lua post-processor respects any session overrides, for example when you use a configuration fragment to update the default parameters.

For example:

    [Eduction]
    PostProcessingDefaultParameters=MyLuaParameters

    [MyLuaParameters]
    Greeting=Hello
    Price=15

This example means that, with no further parameters added programatically, the following Lua post-processing script prints both of these entries passed in `params`:

    function processmatch(edkmatch, params)
       for key, value in pairs(params) do
          print(string.format("%s -> %s", key, value))
       end
       return true
    end

NOTE: The default values that you set apply to all your configured post-processing scripts.
