---------------------------------
Summary: enable kafka broker to remove orphan partitions
automatically
Key: KAFKA-7362
URL: https://issues.apache.org/jira/browse/KAFKA-7362
Project: Kafka
Issue Type: Improvement
Components: core, log
Reporter: xiongqi wu
Assignee: xiongqi wu
When partition reassignment removes topic partitions from a offline broker,
those removed partitions become orphan partitions to the broker. When the
offline broker comes back online, it is not able to clean up both data and
folders that belong to orphan partitions. Log manager will scan all all dirs
during startup, but the time based retention policy on a topic partition will
not be kicked out until the broker is either a follower or a leader of the
partition. In addition, we do not have logic to delete folders that belong to
orphan partition today.
Open this ticket to provide a mechanism (when enabled) to safely remove orphan
partitions automatically.
