lianetm opened a new pull request, #16569: URL: https://github.com/apache/kafka/pull/16569
Improvement to ensure that, even though the leave group request is sent out once, the leave group operation is considered complete only when it receives a response to the HB to leave (successful or failed). The motivation is to avoid undesired interactions with operations triggered after the unsubscribe (ex. consumer close triggers a leave group operation, and shuts down the network thread when it completes, which before this PR could lead to responses to disconnected clients). This is the same behaviour on close that the legacy consumer has (waits for leave responses). Note that this PR does not change the transitions of the state machine on leave group, only the completion of the leave group future. -- This is an automated message from the Apache Git Service.
