--------------------------------------
Summary: Topic IDs should be removed from PartitionFetchState if
they are no longer sent by the controller
Key: KAFKA-13394
URL: https://issues.apache.org/jira/browse/KAFKA-13394
Project: Kafka
Issue Type: Bug
Reporter: Justine Olshan
Assignee: Justine Olshan
With KAFKA-13102, we added topic IDs to the InitialFetchState and the
PartitionFetchState in order to send fetch requests using topic IDs when ibp is
3.1.
However, there are some cases where we could initially send topic IDs from the
controller and then no longer to do so (controller changes to an IBP < 2.8). If
we do not remove from the PartitionFetchState and one broker is still IBP 3.1,
it will try to send a version 13 fetch request to brokers that no longer have
topic IDs in the metadata cache. This could leave the cluster in a state unable
to fetch from these partitions.
