>             Project: Kafka
>          Issue Type: Improvement
>          Components: core
>    Affects Versions: 0.10.1.0
>            Reporter: Jiangjie Qin

> [~junrao] brought up the following scenario: 
> If users are pumping data with timestamp already passed log.retention.ms into Kafka,
the messages will be appended to the log but will be immediately rolled out by log retention
thread when it kicks in and the messages will be deleted. 
> To avoid this produce-and-deleted scenario, we can set the default value of log.message.timestamp.difference.max.ms
to be the same as log.retention.ms.
