---------------------------------------
Summary: Add logic to fence kraft brokers which have fallen behind
in replication
Key: KAFKA-14152
URL: https://issues.apache.org/jira/browse/KAFKA-14152
Project: Kafka
Issue Type: Improvement
Reporter: Jason Gustafson
When a kraft broker registers with the controller, it must catch up to the
current metadata before it is unfenced. However, once it has been unfenced, it
only needs to continue sending heartbeats to remain unfenced. It can fall
arbitrarily behind in the replication of the metadata log and remain unfenced.
We should consider whether there is an inverse condition that we can use to
fence a broker that has fallen behind.
