Assume that three consumers of a certain group want to connect to a broker for a topic with 3 partitions. After the FindCoordinator API is done, the consumers send JoinGroup. Since the broker cannot know in advance how many consumers are expected to join, it waits group.initial.rebalance.delay.ms before starting a rebalance.
Therefore, does this mean the JoinGroup API response of each request is "held" until the waiting period is over? Best regards.
