Why fix client_id as 'kafka-php'? client_id is used in many scenarios.
I think this is a mistake
@icepigss would you like to try to implement the possibility of changing the client-id?
In my case, I need to change it because the server is restricted.
Other than that, don't you find it a little weird that i change it but no effect.
$config->setClientId("my_client");
@icepigss I completely get your point and frustration. What I meant is that this is an open source library driven by the needs of the people who created it. So far nobody needed this feature, thus we don't have it.
Please take this as an invite to collaborate with us in this piece of software and get your need addressed in a more appropriated timeframe for you =)
