Bertus Greeff commented on KAFKA-7061:
--------------------------------------
There is discussion of this KIP on the Kafka Dev mailing list. Suggest you
look there.
I should point out that the reason that I want this feature is addressed in an
even better way by Transactions. See the part on Zombie Fencing here:

> Enhanced log compaction
> -----------------------
>
> Key: KAFKA-7061
> URL: https://issues.apache.org/jira/browse/KAFKA-7061
> Project: Kafka
> Issue Type: Improvement
> Components: core
> Affects Versions: 2.0.0
> Reporter: Luis Cabral
> Priority: Major
> Fix For: 2.1.0
>
>
> Enhance log compaction to support more than just offset comparison, so the
> insertion order isn't dictating which records to keep.
> Default behavior is kept as it was, with the enhanced approached having to be
> purposely activated.
> The enhanced compaction is done either via the record timestamp, by settings
> the new configuration as "timestamp" or via the record headers by setting
> this configuration to anything other than the default "offset" or the
> reserved "timestamp".
> See
> [KIP-280|https://cwiki.apache.org/confluence/display/KAFKA/KIP-280%3A+Enhanced+log+compaction]
> for more details.
