cmccabe opened a new pull request, #19745: URL: https://github.com/apache/kafka/pull/19745
Previously, we could wait for up to half of the broker session timeout for an RPC to complete, and then delay by up to half of the broker session timeout. When taken together, these two delays could lead to brokers erroneously missing heartbeats. This change removes exponential backoff for heartbeats sent from the broker to the controller. The load caused by heartbeats is not heavy, and controllers can easily time out heartbeats when the queue length is too long. Additionally, we now set the maximum RPC time to the length of the broker period. This minimizes the impact of heavy load. -- This is an automated message from the Apache Git Service.
