Matthias J. Sax updated KAFKA-8411:
-----------------------------------
Priority: Minor (was: Major)
> Option to keep tombstones forever in compacted logs
> ----------------------------------------------------
>
> Key: KAFKA-8411
> URL: https://issues.apache.org/jira/browse/KAFKA-8411
> Project: Kafka
> Issue Type: Improvement
> Components: log cleaner
> Reporter: Lukas Welte
> Priority: Minor
>
> 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.
