------------------------------
Summary: supporting replication.throttled.replicas in dynamic
broker configuration
Key: KAFKA-7983
URL: https://issues.apache.org/jira/browse/KAFKA-7983
Project: Kafka
Issue Type: New Feature
Components: core
Reporter: Jun Rao
In
[KIP-226|https://cwiki.apache.org/confluence/display/KAFKA/KIP-226+-+Dynamic+Broker+Configuration#KIP-226-DynamicBrokerConfiguration-DefaultTopicconfigs],
we added the support to change broker defaults dynamically. However, it didn't
support changing leader.replication.throttled.replicas and
follower.replication.throttled.replicas. These 2 configs were introduced in
[KIP-73|https://cwiki.apache.org/confluence/display/KAFKA/KIP-73+Replication+Quotas]
and controls the set of topic partitions on which replication throttling will
be engaged. One useful case is to be able to set a default value for both
configs to * to allow throttling to be engaged for all topic partitions.
Currently, the static default value for both configs are ignored for
replication throttling, it would be useful to fix that as well.
