-----------------------------------
Summary: Broker could cache its overlapping ApiVersions with
active controller
Key: KAFKA-12215
URL: https://issues.apache.org/jira/browse/KAFKA-12215
Project: Kafka
Issue Type: Improvement
Reporter: Boyang Chen
Right now, each ApiVersionRequest would need to compute overlapping api
versions with controller every time:
https://issues.apache.org/jira/browse/KAFKA-10674
Unless the active controller is changed, the computation result should always
be the same. We may consider cache the result and only update it when the
controller change happens.
