------------------------------------
Summary: KRaft Controller doesn't allow metadata updates before
migration starts
Key: KAFKA-14805
URL: https://issues.apache.org/jira/browse/KAFKA-14805
Project: Kafka
Issue Type: Sub-task
Components: kraft
Reporter: David Arthur
Fix For: 3.5.0, 3.4.1
When starting a ZK to KRaft migration, the new KRaft quorum should not accept
external metadata updates from things like CreateTopics or AllocateProducerIds.
Having metadata present in the log prior to the migration can lead to undefined
state, which is not great.
This is currently causing test failures on trunk because some producer is
allocating a producer ID between the time the KRaft quorum starts and the
migration starts.
