---------------------------------------
Summary: Change the default of
log.message.timestamp.difference.max.ms to 500 years
Key: KAFKA-6939
URL: https://issues.apache.org/jira/browse/KAFKA-6939
Project: Kafka
Issue Type: Improvement
Reporter: Badai Aqrandista
If producer incorrectly provides timestamp in microsecond (not in millisecond),
the record is accepted by default and can cause broker to roll the segment
files continuously. And on a heavily used broker, this will generate a lot of
index files, which then causes the broker to hit `vm.max_map_count`.
So I'd like to suggest changing the default for
log.message.timestamp.difference.max.ms to 15768000000000 (500 years * 365 days
* 86400 seconds * 1000). This would reject timestamp in microsecond from
producer and still allow most historical data to be stored in Kafka.
