> I consum from kafka sink to kafka,Then I split the message into then pieces.I guess the ten message should in one transaction. When the fifth message is sink kafka ,I throw a exception.but the first four are already in kafka.
> I set some parameters :
>        properties.setProperty("transactional.id", "cxx");
>         properties.setProperty("ack", "all");
>         properties.put("enable.idempotence",true);
>         properties.put("max.in.flight.requests.per.connection",5);
>         properties.put("retries", 2);
>         properties.setProperty("client.id", "producer-syn-2");
