Ning Liu commented on KAFKA-7061:
---------------------------------
I plan to revive this thread. The target is to make the compaction strategy
config per topic. Will use whatever is valuable from the hanging PR to complete
this task. The update on KIP design will be provided shortly.
> 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
> Assignee: Ning Liu
> Priority: Major
> Labels: kip
>
> 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.
