how to limit rate in Producer ?

[le-cardinal]

Hello,

is there an easy way to limit rate of produced messages per second on my producer app ?

i saw some code in rdkafka_performance to simulate somekind of timeout by looping with a rd_kafka_poll() but i'm not convinced by that. In addition, it is using some macros from some others files, so it's very hard to implement the same thing on a real producer that does not include all rd*.h files. My idea is to have some code to slow down/speed up the emission rate on my producer app to see up to which rate there is no errors (all messages acknowledged, no errors encoutered).

Any help/idea will be highly appreciated.

regards
