Hi, Have you checked if the error during normal execution, or right after failover? Best, Yun

Hi, after failover still OutOfOrderSequenceException. when I close checkpoint, kafka broker still return OutOfOrderSequenceException to me . At 2021-06-04 17:52:22, "Yun Gao" <[hidden email]> wrote:

Hi, I tried google and found one possible related issue in [1]. Could you try to remove the config properties.setProperty(ProducerConfig.RETRIES_CONFIG, "5"); and try again ? Best, Yun
