May i know if you want to keep the fields in sdc.properties file and wants to use it streamsets ?

If that is the case then declare the variables in the properties files and try to use  like ${id} .

 If that is not the case , kindly provide some example so i can have a look and try to find  resolution for the use case.

Thanks & Regards

Ya bikram same thing I want to put field in sdc.properties file and wants to use in streamsets. I have tried also , I will give one example I have put variable like runtime.conf_p_artist_type=type and in streamsets I am providing name like /*/${runtime:conf(‘p_artist_type’)}]  as per documentation but it is not working.

Kindly check if the parameters are still available in sdc.properties file after restarting data collector.

I noticed that after restart its replacing with new sdc.properties file in SDC and i believe that is reason the value couldn’t recognise in

${runtime:conf(<property name>)}
