----------------------------------
Summary: 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
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.
