>                 Key: KAFKA-8411
>                 URL: https://issues.apache.org/jira/browse/KAFKA-8411
>             Project: Kafka
>          Issue Type: Improvement
>          Components: log cleaner

> Log compaction is great to balance between having all data in a topic and reducing the amount of messages in a topic.
> However the delete tombstones are cleaned after a certain period. For some use cases we would really like to keep the latest message of each key, which means also the tombstone of that ID should be kept forever.
> An option to configure _delete.retention.ms_ to e.g. _-1_ to enable this functionality would be great.
