> 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.
