-------------------------------------
This has actually been down. We used one ticket to finish the task in three
tickets. I'll clean it up.
> KIP-32 (part 2): Changes in broker to over-write timestamp or reject message
> ----------------------------------------------------------------------------
>
> Key: KAFKA-3026
> URL: https://issues.apache.org/jira/browse/KAFKA-3026
> Project: Kafka
> Issue Type: Sub-task
> Reporter: Anna Povzner
> Assignee: Jiangjie Qin
>
> The decision about this JIRA assignment is still under discussion with
> [~becket_qin]. Not going to implement without his agreement.
> This JIRA includes:
> When the broker receives a message, it checks the configs:
> 1. If message.timestamp.type=LogAppendTime, the server over-writes the
> timestamp with its current local time
> Message could be compressed or not compressed. In either case, the timestamp
> is always over-written to broker's current time
> 2. If message.timestamp.type=CreateTime, the server calculated the difference
> between the current time on broker and Timestamp in the message:
> If difference is within max.message.time.difference.ms, the server will
> accept it and append it to the log. For compressed message, server will
> update the timestamp in compressed message to -1: this means that CreateTime
> is used and the timestamp is in each individual inner message.
> If difference is higher than max.message.time.difference.ms, the server will
> reject the entire batch with TimestampExceededThresholdException.
> (Actually adding the timestamp to the message and adding configs are covered
> by KAFKA-3025).
