> In our production environment, when we consume kafka's topic data in an
> operating program, we found an error:
> org.apache.kafka.common.KafkaException: Record for partition
> rl_dqn_debug_example-49 at offset 2911287689 is invalid, cause: Record is
> corrupt (stored crc = 3580880396, computed crc = 1701403171)
> By looking at the code, I found that in some cases kafka would not verify the
> data and write it to disk, so we fixed it.
