我读了Kafka: Continuously getting FETCH_SESSION_ID_NOT_FOUND和How to check the actual number of incremental fetch session cache slots used in Kafka cluster?
目前,我们刚刚获得了有关Burrow的滞后指标。
我的问题:
1,有人可以解释为什么我有这么多FETCH_SESSION_ID_NOT_FOUND
吗?这是什么意思?我以前没买。
有些消费者发送太多请求?还是领导人总是连任?
我不知道。可以给我更多细节吗?
2,如果是因为某些消费者发送了太多请求,那么如何识别这些消费者?
谢谢
