-------------------------------
Summary: Prevent log corruption in case of OOM
Key: KAFKA-6488
URL: https://issues.apache.org/jira/browse/KAFKA-6488
Project: Kafka
Issue Type: Bug
Reporter: Dong Lin
Assignee: Dong Lin
Currently we will append the message to the log before updating the LEO.
However, if there is OOM in between these two steps, KafkaRequestHandler threadÂ
can append a message to the log without updating the LEO. The next message may
be appended with the same offset as the first message. This can prevent broker
from being started because two messages have the same offset in the log.
