Wenbing Shen commented on KAFKA-10889:
--------------------------------------
[~becket_qin] Why not isolate the message creation time from the log append
time,return the creation time for the client,and use the log append time
between brokers,which is more friendly to log cleanup.
> The log cleaner is not working for topic partitions

> * I have a topic that is reserved for the default of 7 days, but the log
> exists from October 26th to December 25th today.The log cleaner doesn't seem
> to be working on it.This seems to be an underlying problem in Kafka.
