---------------------------------
[~ijuma] Yes. I have not thought about how to do this yet. Just want to create
a ticket to document the possible improvement here.
> Producer should negotiate message format version with broker

> Project: Kafka
> Issue Type: Improvement
> Reporter: Dong Lin
> Assignee: Dong Lin
> Priority: Major
>
> Currently Producer will always send the record with the highest magic format
> version that is supported by both the produce and broker library regardless
> of log.message.format.version config in the broker.
> This causes unnecessary message downconvert overhead if
> log.message.format.version has not been upgraded and producer/broker library
> has been upgraded. It is preferred for produce to produce message with format
> version no higher than the log.message.format.version configured in the
> broker.
