Rebased onto the latest trunk and I reviewed the problem more carefully and here is the summary: 1. As @kkonstantine stated, [the default value of `retries` config is `Integer.MAX_VALUE`](https://github.com/apache/kafka/blob/trunk/clients/src/main/java/org/apache/kafka/clients/producer/ProducerConfig.java#L289); however, the documentation still states that **'though since we have specified <code>retries</code> as 0 it won't.'** It seems like `props.put("retries", 0);` was removed mistakenly from example code snippet in commit c3e7c0b (2.1.0). 2. The default value of `linger.ms` config is 0; however, the current documentation states that **we set our linger time to 1 millisecond**. `linger.ms` was removed from example code snippet in commit 975b680 (2.2.0), for the example code of that times violates `delivery.timeout.ms` (30000) >= `linger.ms` (1) + `request.timeout.ms` (30000 by default). However, it should not have be removed since removing `delivery.timeout.ms` only was enough - `delivery.timeout.ms` defaults to 120000. In conclusion, it seems like `props.put("linger.ms", 1);` was also removed mistakenly. cc for the reviewers of commit c3e7c0b and 975b680. @ijuma @guozhangwang @hachikuji ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
