---------------------------------------

             Summary: Change the default of log.message.timestamp.difference.max.ms to 500 years
                 Key: KAFKA-6939
                 URL: https://issues.apache.org/jira/browse/KAFKA-6939
             Project: Kafka
          Issue Type: Improvement
            Reporter: Badai Aqrandista


If producer incorrectly provides timestamp in microsecond (not in millisecond), the record is accepted by default and can cause broker to roll the segment files continuously. And on a heavily used broker, this will generate a lot of index files, which then causes the broker to hit `vm.max_map_count`.

So I'd like to suggest changing the default for log.message.timestamp.difference.max.ms to 15768000000000 (500 years * 365 days * 86400 seconds * 1000). This would reject timestamp in microsecond from producer and still allow most historical data to be stored in Kafka.
