------------------------------------
Summary: Compacted topic could be misused up to fill a disk;
Key: KAFKA-5201
URL: https://issues.apache.org/jira/browse/KAFKA-5201
Project: Kafka
Issue Type: Improvement
Reporter: Edoardo Comar
Misuse of a topic with cleanup policy = compact
could lead to a disk being filled if a misbehaving producer keeps producing
messages with unique keys.
The mixed cleanup policy compact,delete could be adopted, but would not
guarantee that the latest "legitimate" keys will be kept.
It would be desirable to have a cleanup policy that attempts to preserve
messages with 'legitimate' keys
This issue needs a KIP but I have no proposed solution yet at the time of
writing.
