thanks for reply. conf.Producer.Retry.MaxBufferBytes setting control retry send message on retryHandler(), it works only when produce to one broker error(e.g. greater thanMaxRequestSize/MaxMessageBytes/Flush.MaxMessages). what i need is control the max memory usage in client, no matter how many brokers(e.g. 30 brokers) or topics (e.g. 100 topics), this feature doesn't work in my scenario.
