Is it possible to change parameter num.of.producers via config file or command line arguments?

Hi to all!
@yangy0000 - I found parameter num.of.producers in file
uReplicator-Worker/src/main/java/com/uber/stream/ureplicator/worker/Constants.java, but it is only listed in this file.
Is it possible to change the number of producers by changing this parameter num.of.producers via a some config file or command line argument?
I tried adding it to the configuration file helix.properties - but nothing came of it, num.of.producers was not taken to work.

Or the only option is to change num.of.producers in the source file
uReplicator-Worker/src/main/java/com/uber/stream/ureplicator/worker/Constants.java
and then build it?

I would be glad to hear any advice, thanks.

yes, you can change num.of.producers in producer.properties

@yangy0000 - that's how - understood, thank you very much for the explanation!
I will check this. That is, producer.properties would look something like this?
